Question

In an electrical circuit, the unit of potential difference between the ends of a resistance is:

• A. Ohm
• B. Ampere
• C. Volt
• D. Watt

Hint:

The potential difference (Voltage) across a resistor is calculated by Ohm's law: \(V = IR\), where \(I\) is the current, and \(R\) is the resistance.

Answer 1

The Correct Option is C

The unit of potential difference (also called voltage) is the Volt (V). The potential difference is defined as the work done per unit charge in moving a charge between two points. The unit of resistance is Ohm, and the unit of current is Ampere.
