Question

The current in the 120 \( \Omega \) resistor shown in the circuit is

• A. 2 A
• B. 3 A
• C. 6 A
• D. 2.5 A

Hint:

Always use Ohm’s Law to calculate current when voltage and resistance are known.

Answer 1

The Correct Option is B

Step 1: Apply Ohm’s Law.
From Ohm’s Law, the current \( I \) is given by: \[ I = \frac{V}{R} \] where \( V \) is the voltage and \( R \) is the resistance.

Step 2: Substitute the values.
Given \( V = 36 \, \text{V} \) and \( R = 120 \, \Omega \), the current is: \[ I = \frac{36}{120} = 0.3 \, \text{A} \]
