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

An electric lamp is rated 40 W, 100 V. Find the current in the lamp and the resistance of the lamp.

Two incandescent lamps (25 W , 120 V ) and (100W , 120 V ) are connnected in series across a 240 V supply . Assuming that the resistances of the lamps do not vary with current ,find the power dissipated in each lamp after the connection .

What are the advantages of fluroscent lamps over incandescent lamps.

A 75 W lamp is designed to be used on 15 V. What is its resistance? If the lamp is to be used on 120 V, what resistance must be connected in series with it?

An electric lamp is marked 60 W, 240 V. If it operats at 200, V the current through it will be
