Question

Calculate the resistance of an electric bulb which allows a 10 A current when connected to a 220 V power source.

Solution

Current flowing through the electric bulb, I = 10 A
Voltage of the source in the circuit, V = 220 V
According to Ohm’s law,
V=IR
Where, R is the resistance of the electric bulb

`R=V/I=220/10=22`Ω
Therefore, the resistance of the electric bulb is 22 Ω.

 

  Is there an error in this question or solution?
