If you live in Al Faseel and Physics is becoming difficult for you, then you are not alone. Many students attend school regularly, complete homework, read textbooks, and still feel confused when numerical questions, diagrams, derivations and conceptual applications come in Physics. This problem becomes more serious for students preparing for NEET, IIT JEE, CBSE, A-Level, AP Physics, IB Physics or IGCSE Physics because Physics is not a subject that can be mastered only by memorising definitions.
Physics needs concept clarity, mathematical confidence, diagram understanding and regular numerical practice. This is where Kumar Sir from Kumar Physics Classes can help students build a strong foundation from the basic level.
At Kumar Physics Classes, every topic is explained step by step. First, Kumar Sir explains the physical meaning of the concept. Then he explains the formula, units, graph, derivation and finally numerical applications. This method helps students understand Physics deeply instead of simply memorising formulas.

Why Physics Becomes Difficult for Students
Physics becomes difficult when students learn formulas without understanding their origin. For example, in mechanics, students may remember equations of motion but fail to understand displacement, velocity, acceleration and force. In electricity, students may remember Ohm’s law but struggle when circuits become complex. In optics, they may remember lens formula but fail to draw ray diagrams correctly.
The real difficulty is not Physics itself. The difficulty comes from weak fundamentals. If the basic concept is clear, Physics becomes logical and interesting.
How Kumar Sir Teaches Physics
Kumar Sir teaches Physics in a very systematic way. He begins with the basic idea of the topic and connects it with real-life examples. After that, he explains the mathematical form of the concept. Then he discusses important formulas, graphs, derivations and numerical problems.
His teaching style is especially useful for students who say:
I understand theory but cannot solve numericals.
I forget formulas during exams.
I cannot understand derivations.

Kumar Sir helps A-Level students understand each topic with diagrams, formulas, derivations and exam-style questions. He also focuses on practical-based understanding and graph interpretation.
A-Level students often struggle because questions are application-based. Kumar Sir trains students to read the question carefully, identify the concept and present the answer correctly.
Physics Tutor in Al Faseel for IB Physics
IB Physics is concept-heavy and requires strong explanation skills. Students need to understand theory, data analysis, graphs, uncertainty, internal assessment and application-based questions.
Kumar Sir helps IB students develop clarity in concepts and confidence in problem solving. He explains topics like measurements, mechanics, thermal Physics, waves, electricity, magnetism, circular motion, gravitation, atomic Physics and energy production.
IB Physics students need more than formula practice. They need conceptual writing and analytical thinking. Kumar Sir helps students improve both.
Physics Tutor in Al Faseel for AP Physics
AP Physics requires a strong understanding of concepts and mathematical applications. Students preparing for AP Physics 1, AP Physics 2, AP Physics C Mechanics or AP Physics C Electricity and Magnetism need proper guidance.
Kumar Sir explains AP Physics with step-by-step reasoning. He helps students understand free-body diagrams, energy conservation, momentum, torque, circuits, electric fields, magnetic fields and calculus-based Physics where required.
Physics Tutor in Al Faseel for IGCSE Physics
IGCSE Physics builds the foundation for higher-level Physics. Students must understand basic concepts clearly so that they can perform well in exams and later move confidently to A-Level or IB Physics.

If Physics is becoming difficult, do not wait until the exam comes near. Start early, build concepts properly and practise regularly. With the right guidance, Physics can become one of the most scoring subjects.
Properties of Resistance
Resistance opposes current in a conductor.
SI unit of resistance is ohm (Ω).
Formula: R = V / I.
Resistance depends on length, area, material and temperature.
For a uniform wire: R = ρL/A
ρ = resistivity
L = length
A = area of cross-section
Effect of Length
If length increases, resistance increases.
R ∝ L
So, a longer wire has more resistance because electrons face more collisions while travelling.
Effect of Thickness / Area
If thickness or cross-sectional area increases, resistance decreases.
R ∝ 1/A
So, a thick wire has less resistance because more space is available for current flow.
Effect of Temperature on Metals
For metals, when temperature increases, resistance increases.
Reason: metal ions vibrate more at higher temperature, so electrons suffer more collisions.
Rₜ = R₀(1 + αΔT)
Effect of Temperature on Insulators
In insulators, resistivity is very high. When temperature increases, resistivity generally decreases slightly because some electrons may get enough energy to move, but still current remains very small.
Effect of Temperature on Semiconductors
In semiconductors, when temperature increases, resistance and resistivity decrease.
Reason: more electrons jump from valence band to conduction band, so number of charge carriers increases.
So:
Metals: temperature ↑ → resistance ↑
Semiconductors: temperature ↑ → resistance ↓
Insulators: temperature ↑ → resistivity may decrease, but still remains very high
Final Summary Table
| Factor | Effect on Resistance |
|---|---|
| Length increases | Resistance increases |
| Area/thickness increases | Resistance decreases |
| Temperature increases in metals | Resistance increases |
| Temperature increases in semiconductors | Resistance decreases |
| Temperature increases in insulators | Resistivity decreases slightly but remains very high |
In an ammeter, voltmeter, potentiometer and meter bridge, the wire is generally made of alloys like constantan or manganin. These alloys are preferred because their electrical properties remain almost stable with temperature.
The main reason is that constantan and manganin have comparatively high resistivity compared to pure metals like copper or aluminium. Because of high resistivity, even a small length of wire can provide suitable resistance. This helps in making compact and accurate electrical instruments.
Another very important property is their very low temperature coefficient of resistance. It means that when temperature increases, their resistance and resistivity do not change much. In electrical measuring instruments, current passes through the wire and produces some heating. If the resistance changed a lot with temperature, the reading of the instrument would become wrong. But in manganin and constantan, resistance remains nearly constant, so the instrument gives more accurate readings.
Pure metals like copper have low resistivity, but their resistance changes noticeably with temperature. Therefore, copper is not suitable for standard resistance coils in measuring instruments. Copper is good for connecting wires because it offers very low resistance, but it is not good where a fixed resistance is required.
Manganin is commonly used in resistance boxes, standard resistors and meter bridge wires because it has high resistivity and very small temperature coefficient. Constantan is also used in potentiometer wires and resistance wires for the same reason.
So the important points are:
Constantan and manganin have high resistivity.
Their resistance does not change much with temperature.
They give stable and accurate readings.
They are better than pure metals for resistance wires.
Copper is used for connecting wires, but not for standard resistance.
That is why in instruments like potentiometer, meter bridge, ammeter and voltmeter, alloys such as manganin and constantan are used instead of pure metals.
