Question

the voltmeter shown inthe figure reads 18v across the 50ohm resistors .find the resistance of the voltmeter

Answer 1

The voltage across the 24 ohms resistor is 30 - 18 = 12 v 

The current flowing is 12 v / 24Ω = 0.5 A 

The current through the 50 Ω resistor is 18v / 50Ω = 0.36 A 

So the current through the voltmeter is 0.5A - 0.36 A = 0.14 A 

The resistance of the voltmeter is 18 v / 0.14 A = 128.6 Ω
