Question
A voltmeter reading up to 1000 mV is calibrated by a potentiometer. An emf of 1.08 V is balanced across 5.4 m length of the wire. When voltmeter reading is 0.9 V, the balancing length is 4.55 m. The error in the voltmeter reading is :
- 0 V
- –0.001 V
- –0.1 V
- –0.01 V
The correct answer is: –0.01 V
