Question

what would be the reading of ammeter and voltmeter in the given circuit?

Answer 1

Total Resistance (all in series ) = sum of each = 1+3+2= 6 ohm

V of battery = 3 V

By Ohm's Law, we have : at a constant temperature:

V=IR

I = R/V

I = 6/3 = 2 A

Since the same amount of current passes through each resistor and out in the series circuit, Ammeter will read = 2 A

at across the voltmeter, AB :

I = 2 A

R = 1 ohm

V = I R

V = 2×1 = 2 V

Therefore, the voltmeter will read 2 V

Answer 2

I hope you understand
