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:
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 = 
R = 
R = 5
