A current of 1A flow when an electric bulb is connect to 220 V mains. What would be the current when the same bulb is connected to 110 V mains?

A 220 V -60W electric bulb is connected in 220 V line . What is the resistance of the filament of the bulb , when it is tured on ?

An electric bulb is connected to battery of e.m.f. 10V and 0.01 A current is flowing through the bulb. But when it is connected to 220V mains then the cureent is 0.05 A. Explain this apparent discrepancy with ohm's law.

A current of 1 A flows in a coll when connected to a 100 V dc source. IF the same coll is connected to a 100 V, 50 Hz ac source, a current od 0.5 A flows in the coll. Calculate the inductance of the coll.

An electric kettle has a resistance of 160 Omega . What current will flow when it is connected to a 240 V supply?

An electric bulb marked as 50 W-200 V is connected across a 100 V supply. The present power of the bulb is

A few electric bulbs are connected in series to the 220 V mains . One bulb fused , the remaining bulbs are again put in series and connected to the same supply of 220 V. In which case will the bulbs glow brighter and why ?

The power of a bulb connected to 120V mains is 60W.What will be its power for 220V mains:

When an ideal choke is connected to an ac source of 100V and 50Hz, a current of 8 A flows through the circuit, A current of 10 A flows throught the circuit when a pure resistor is connected instead of the choke coil. IF the two are connected in series with an ac supply of 100 V and 40 Hz, then the current in the circuit is

A 220 V - 60 W electric lamp os connected to 220 V supply line . Determine the resistance of the lamp in incandescent state .
