Question

Write the S.I. unit of: (i) Electric potential difference (ii) Resistance

Hint:

Make sure you know the units for all basic electrical quantities: Current (Ampere), Charge (Coulomb), Power (Watt).

Answer 1

Step 1: Understanding the Concept:
Standard units are crucial in physics to quantify electrical properties.

Step 2: Detailed Explanation:
(i) Electric potential difference: Also known as voltage, it measures the work done per unit charge. Its S.I. unit is the Volt (symbol: V).
(ii) Resistance: It is the opposition to current flow. Its S.I. unit is the Ohm (symbol: \(\Omega\)).

Step 3: Final Answer:
The units are Volt and Ohm respectively.
