Question

A current of 2 A flows through a conductor with a resistance of 5 \(\Omega\). Calculate the potential difference across the conductor.

• A. 10 V
• B. 5 V
• C. 2 V
• D. 20 V

Hint:

Ohm's law relates the current, voltage, and resistance in an electrical circuit. Make sure to use consistent units when applying this law.

Answer 1

The Correct Option is A

Using Ohm’s law, which states: \[ V = IR \] Where: - \( I = 2 \, \text{A} \) is the current, - \( R = 5 \, \Omega \) is the resistance. Now, substitute the values: \[ V = 2 \times 5 = 10 \, \text{V} \] Thus, the potential difference across the conductor is \( 10 \, \text{V} \).
