one heating coil takes 8 minutes to boil a quantity of water electrically . Now the heating coil is cut into two equal parts which are joined parallel to each other . This parallel combination will heat the same amount of water in how many minutes?

time taken by heating one  coil to  boil water=8 minutes

when one coil divides into two coils 2 the heat of each coil remains same as it was of coil before division into two parts

hence two coil will take half time to boil water.

8/2=4 minutes
