Total resistance = 20+8 = 28 ohm
Current flowing,
V = 220V( standard voltage in India)
R = 28 ohm
I = V/R
I = 220/28
I = 7.85 A
Current flowing,
V = 220V( standard voltage in India)
R = 28 ohm
I = V/R
I = 220/28

a) the total resistance of circuit = 20 + 8
= 28 ohm
b) The current flowing through the circuit
= Voltage appllied/ Voltage of the battery
=8/28
The current through the circuit = 0.28 amp
