Physics Tutor in VIP Road Surat
+91-9958461445
VIP Road Surat is one of the most premium and fast-developing areas of Surat. Families living around VIP Road, Vesu, Bharthana, Dumas Road and nearby premium societies usually give strong importance to education, career and professional success. But even in such a developed area, many students struggle badly in Physics.
A student may be studying in a good school, attending coaching, watching online videos and solving notes, but still Physics may not enter the mind properly. The reason is simple: Physics is not a subject of memorising lines. Physics is a subject of concepts, imagination, diagrams, logic and step-by-step thinking.
This is why many students searching for Physics Tutor in VIP Road Surat finally need a teacher who can explain Physics from the foundation.
In Current Electricity, students often get confused in nodes, branches, meshes, potential difference and circuit simplification. If two points are connected by an ideal wire, both points are at the same potential. That wire can be squeezed and treated as one single point. This one idea can simplify many difficult circuits. But if this idea is not clear, even simple circuit questions look dangerous.
Kumar Sir explains these concepts slowly, clearly and practically. He teaches how to identify equal-potential points, how to redraw a circuit, how to apply Kirchhoff Current Law, how to apply Kirchhoff Voltage Law and how to calculate potential difference between two points.

Open Circuit, Short Circuit & EMF
40 Conceptual Questions with Answers
Open Circuit: Current is zero, terminal voltage equals EMF.
Short Circuit: External resistance is almost zero, current becomes maximum.
EMF: Maximum potential difference of a cell when no current is drawn.
Formula: V = E - Ir
Ans: A circuit in which the path is broken and current does not flow.
Ans: Current is zero.
Ans: It is equal to EMF of the cell.
Ans: Because current is zero, so internal drop Ir is zero.
Ans: A circuit in which terminals are connected by very low resistance.
Ans: Current becomes very large.
Ans: Maximum current drawn from a cell, equal to E/r.
Ans: Large current produces excessive heating.
Ans: Energy supplied by cell per unit charge.
Ans: No, only when current is zero.
Ans: Potential difference across external terminals of a cell.
Ans: Because some voltage is lost across internal resistance.
Ans: Resistance inside the cell due to electrolyte and electrodes.
Ans: V = E - Ir.
Ans: Internal voltage drop of the cell.
Ans: In open circuit, because I = 0.
Ans: Nearly zero.
Ans: Internal resistance of the cell.
Ans: Current would become extremely large theoretically.
Ans: A straight line with negative slope.
Ans: V = E - Ir.
Ans: EMF of the cell.
Ans: Short circuit current E/r.
Ans: Slope = -r.
Ans: Because internal drop Ir increases.
Ans: Yes, approximately, when connected in open circuit condition.
Ans: To draw negligible current.
Ans: It draws current and changes the reading.
Ans: Very little current flows, so energy delivery is almost zero.
Ans: Inside the cell as heat due to internal resistance.
Ans: Due to high current through internal resistance.
Ans: A complete circuit where current flows through external resistance.
Ans: Generally yes, because no current flows.
Ans: No, it can damage cell and wires.
Ans: It becomes nearly zero.
Ans: Because external resistance is almost zero.
Ans: EMF is source energy per charge; terminal voltage is available output voltage.
Ans: Because it is measured when no current is drawn.
Ans: Higher EMF or lower internal resistance.
Ans: Open circuit: I = 0, V = E. Short circuit: R = 0, I = E/r.
