Question

An electric lamp of resistance 20 ohm and a resistor of a resistance 8 ohm are connected in series to a 8 volt battery calculate total resistance of the circuit and electric current flowing through the circuit

Answer 1

Answer:

1. If the resistor connected in series we can simply add them together to get the total resistance,

Total Resistance = 20 +8

Total Resistance = 28 ohm

Explanation:

2. By using Ohm's law

V = IR

8 = 1 x 28

I = 0.286A
