Question

A lamp of resistance 20 ohm and conductor of resistance 8 ohm are connected with a battery of 8v in series . Calculate the:1.Total resistance in the circuit 2.Current flowing through the circuit

Answer 1

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

2. By using Ohm's law

    V = IR

    8 = I x 28

    I = 0.286A

Answer 2

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
