Question

What is the value of resistance in the following circuit based on the readings of the ammeter and voltmeter?

5 Ω
0.2 Ω
0.5 Ω
2 Ω

hint Hint:

Resistance of an object is defined as the ration of voltage and current.

The correct answer is: 5 Ω

Given,
Voltage = 10 V
Current = 2 A
We know that,
R = $V over I$
R = $10 over 2$
R = 5 $capital omega$
