In the circuit shown the resistance of voltmeter is `10000 ohm` and that of ammeter is `20 ohm`. The ammeter reading is `0.10 amp` and voltmeter reading is 12 volts. Then `R` is equal to

A

`122 Omega`

B

`140 Omega`

C

`116 Omega`

D

`100 Omega`

Text Solution

Verified by Experts

The correct Answer is:
D
(d) `20 + R = (12)/(0.1) implies R = 100 Omega`
