Question

An electric lamp of resistance 20 ohm and a conductor of resistance 4 ohm are connected to a 6V battery as
Calculate :
(a) the total resistance of the circuit.
(b) the current through the circuit.
(c) the potential difference across the (i) electric lamp and (ii) conductor, and
(d) power of the lamp.
​

Answer 1

• total resistance 24 ohm
• current is 0.25
• potential difference

1. 5 volt
2. 1 volt

• 1.5 watt
