A d.c voltmeter has a sensitivity of 1000Ω/ volt. When it measures half full scale in 100 V range, the current through the voltmeter will be ________mA
-
- 50
- 51
- 47.7
- 5.0
Correct Option: A
Sensitivity of d.c. voltmeter = 1000 Ω/volt For half scale in 100 V range, i.e. 50 V current through the voltmeter,
I = | = 50mA | |
1000 |
