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

An electric lamp of 200 ohm and a toaster of 100 ohm are connected in parallel to a 220 V electricity source. What will be resistance of an electric iron which when connected to the same electric source permits the same current as the total current flowing through both the appliances described above?

A current of 1 ampere flows in series circuit contains an electric lamp and a conductor of 5 ohm when connected to a 10V battery. Calculate the resistance of the electric lamp. Now if a resistance of 10 ohm is connected in parallel with this series combination, what change in current flowing through 5 ohm conductor and potential difference across the lamp will take place? Give reason.

Calculate the resistance of a bulb rated 100 W, 220V. What is the current flowing in the bulb when connected across a potential difference of 220 V?

An electric bulb is rated 220 V and 100 W. when it is operated on 110 V, the power consumed will be

An electric bulb is rated 220 V and 100 W. When it is operated on 110 V, the power consumed will be -

An electric bulb rated 22V is connected to 220 V-5Hz source. Then, the bulb
