Physics Question on Current electricity

The readings of ammeter and voltmeter in the following circuit are respectively

A

2.7 A, 220 V

B

1.2 A, 120 V

C

2.2 A, 220 V

D

1.5 A, 100 V

Answer

2.2 A, 220 V

Explanation

Solution

VL=Vc\because\, V_{L}=V_{c} it is a resistive circuit V=220VandI=VR=220100=2.2A\therefore\, V=220 V and \, I=\frac{V}{R}=\frac{220}{100}=2.2 A
