New City Light Surat is one of the growing and well-planned areas of Surat, where families give strong importance to education, career and professional success. Students living in New City Light, City Light, Vesu, Piplod, Bhatar, Althan, Ghod Dod Road and nearby areas often prepare for NEET, IIT-JEE, CBSE, Gujarat Board, IB, IGCSE and A-Level Physics.
But one common problem remains the same: many students attend school, coaching classes and online lectures, yet Physics does not become clear. They read the chapter, revise notes, watch videos and solve a few questions, but when a real numerical comes in the exam, confusion starts.
This is where Kumar Physics Classes can help.

Why Students in New City Light Surat Struggle in Physics
Physics is not a subject of memorising lines. It is a subject of understanding situations.
In chapters like Current Electricity, Electrostatics, Capacitors, Magnetism, Mechanics, Rotation and Thermodynamics, students often know the formula but do not know where to apply it.
For example, in Current Electricity, students must understand:
What is a node?
What is a branch?
What is a mesh?
How does current divide?
How does potential change?
What happens during earthing?
How to apply Kirchhoff Current Law?
How to apply Kirchhoff Voltage Law?
How to find potential difference between two points?
Without these basics, even simple circuit questions become difficult.
Node, Branch and Mesh: The Foundation of Circuit Physics
A node is a junction point where two or more circuit elements meet. If a student cannot identify nodes, Kirchhoff Current Law becomes confusing.
A branch is a part of the circuit between two nodes containing an element like resistor, battery or capacitor.
A mesh is a closed loop in a circuit where Kirchhoff Voltage Law is applied.
Many students in New City Light Surat make mistakes because they start solving circuits without marking nodes, branches and meshes properly.
Kumar Sir teaches circuits step by step:
First identify nodes.
Then mark branches.
Then choose current directions.
Then apply KCL at junctions.
Then apply KVL in loops.
Then solve equations logically.
Potential and Earthing
Potential is always measured with respect to a reference point. If only one point potential is asked, we usually take earth as reference.
Earth potential is considered zero.
If we want to find potential difference between point A and point B, we move from one point to another and calculate the algebraic change in potential.
This simple idea becomes very powerful in circuits, capacitors and electrostatics.
Why Kumar Sir for Physics in New City Light Surat?
Kumar Sir focuses on concept clarity, not just formula memorisation. Students are taught how to think in Physics.
At Kumar Physics Classes, students learn:
NEET Physics concepts
IIT-JEE Physics numericals
CBSE Class 11 and 12 Physics
Gujarat Board Physics
IB Physics
IGCSE Physics

Final Message for Parents and Students
If you live in New City Light Surat and Physics is becoming difficult, do not wait until the exam pressure becomes too high.
If your child cannot understand nodes, branches, meshes, potential difference, earthing, circuits, capacitors, mechanics or current electricity, then the problem is not lack of intelligence. The problem is lack of proper concept-based guidance.
Physics can become simple when it is taught in the right way.

Node, Branch, Potential & Cell Graphs
Conceptual Physics Questions with Answers
1. What is a Node?
A node is a junction point in a circuit where two or more circuit elements meet. At a node, current may enter or leave. Kirchhoff Current Law is applied at nodes.
2. What is a Branch?
A branch is the part of a circuit between two nodes containing one or more elements such as a resistor, cell, capacitor or wire.
3. How to Find Potential Between Two Points?
To find potential difference between two points A and B, move from A to B through the circuit and add algebraic potential changes. Across a resistor, potential drops in the direction of current by IR. Across a cell, potential rises from negative terminal to positive terminal by emf.
4. Potential–Current Graph for a Cell
For a cell with emf E and internal resistance r, terminal potential difference is V = E - Ir. Therefore, the graph between V and I is a straight line with negative slope. Intercept on V-axis gives emf E, and slope gives -r.
