Sample Questions

1multiple correct

Which of the following factors affect the resistance of a conductor? (Select all correct answers)

Show answer

Length of conductor, Area of cross-section, Nature of material, Temperature

Resistance depends on length (R ∝ l), area of cross-section (R ∝ 1/A), nature of material, and temperature. Color does not affect resistance.

2multiple choice

What is the unit of electric potential?

Show answer

Volt

The unit of electric potential and potential difference is volt (V). One volt is the potential difference when one joule of work is done to move one coulomb of charge.

3multiple choice

In series combination of resistors, which quantity remains the same?

Show answer

Current

In series combination, current remains the same through all resistors as there is only one path for current flow. Voltage divides among the resistors.

4multiple correct

Which materials are good conductors of electricity? (Select all correct answers)

Show answer

Silver, Copper, Aluminum

Metals like silver, copper, and aluminum have many free electrons and are good conductors. Rubber and glass are insulators with very high resistance.
