Question

The ammeter and voltmeter readings are 2.0 A and 3.0 V respectively. What is the resistance of the resistor R?

• A. $\frac{2}{3}$ Ω
• B. $\frac{3}{2}$ Ω
• C. (3 +2 ) Ω
• D. (3x2) Ω

Answer 1

The correct option is B $\frac{3}{2}$ Ω

By Ohm’s Law,
V = IR
$R=\frac{V}{I}$
Hence,
$R=\frac{3}{2}$ Ω or 1.5 Ω
