Question

The reading of voltmeter in the circuit shown is

V, 402​

Answer 1

Answer:

Equivalent resistance=24 ohms Hence total R=64 ohms, I=0.09375 A 0.09374 A x 40 ohms= 3.75 V Left is 2.25 V which is the reading of the voltmeter.

Answer 2

Answer:

the voltmeter resistance is in parallel to 60Ω , that is 40Ω , so they add up to give req = 60×40/(60+40) = 24Ω

now , total resistance is 40+24 = 64Ω

so, current in the circuit is 6/64 = 3/32A

now voltage around voltmeter is 3/32×(24) = 9/4 = 2.25V
