Question

An electric lamp whose resistance is 20 22 and a conductor of 42 resistance
are connected in series to a 6V battery. Find the current through the circuit and
the potential difference across the electrical lamp and conductor.​

Answer 1

Explanation:

Voltage of battery, i.e. V = 6 V

Resistance of electric lamp, i.e. = 20 ohm

Resistance for the conductor connected in series = = 4 ohm

Total Resistance R = = 20 + 4 = 24

As we know, according to the ohm’s law,

Potential difference V across electric lamp,
