A heater boils certain amount of water in 15 minutes. Another heater boils same amount of water in 10 minutes. Time taken to boil same amount of water when both are used in parallel is

A heater boils certain amount of water in 15 minutes. Another heater boils same amount of water in 10 minutes. Time taken to boil same amount of water when both are used in parallel is

A heater boils certain amount of water in 15 minute . Another heater boils same amount of water in 10 minutes . Time takes to boil same amount of water when both are used in parallel is .

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

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.

One heater coil takes time t_1 to heat a glass of water and another takes time t_2 to heat the same amount of water. How much time will it take to heat the same amount of water when the two are connected in series and when the two are connected in parallel ? voltage applied is same in all cases.

A heater of 220V heats a volume of water in 5 minutes time. A heater of 110V heats the same volume of water. Find time of heating.
