The heat developed in an electric wire of resistance R by a current I for at time t is

Two bulbs, one of 50 watt and another of 25 watt are connected in series to the mains. The ratio of the currents through them is

The maximum current that flows through a fuse wire before it blows out varies with its radius as

A 100 watt bulb working on 200 volt and a 200 watt bulb working on 100 volt have

There are two electric bulbs of 40 W and 100 W. Which one will be brighter when first connected in series and then in parallel

When two resistances R₁ and R₂ are connected in series and parallel with 120 V line power consumed will be 25 W and 100 W respectively. Then the ratio of power consumed by R₁ to that consumed by R₂ will be

Match the List I with the List II from the combination shown. In the left side (List I) there are four different conditions and in the right side (List II), there are ratios of heat produced in each resistance for each condition
