A heater takes 50 minute to boil a given amount of water, its coil is broken in five equal parts. If one part is used, then how much time it will take to boil the same amount of water using the same source?

There are two separate coils in a heater . If one col is used then it takes 20 minutes to boil a given amount of water completely. But when its other coil is used then it takes 5 minutes to boil the same amount of water. Calculate the time taken to boil the same amount of water using the same source when the two coils are connected (1) in series and (2) in parallel.

A coil takes 15 min to boil a certain amount of water, another coil takes 20 min for the same process. Time taken to boil the same amount of water when both coil are connected in series

A coil takes 15 min to boil a certain amount of water, another coil takes 20 min for the same process. Time taken to boil the same amount of water when both coil are connected in series

Two heater coils separately take 10 minutes and 5 minutes to boil a certain amount of water.Find the time taken by both the coils connected in series to boil the same amount of water.

If a heater coil is cut into two equal parts and only one part is used in the heater, the heat generated will be

An electric heater operating at 220 volts boils 5 litre of water in 5 minutes. If it is used on 110 volts, it will boil the same amount of water in

A heater coil is cut into two equal parts and only one part is used in the heater, the heat generated becomes
