Question

A 220 v source is connected to a heater taking current 15 ampere for 10 minutes find the energy consamed by the heater

Answer 1

Answer:

since voltage applied across the heater is 220 volt and the current flowing through it is 15 ampere and the time period for which the current flows is 10x60 seconds so by using the formula energy consumed by the heater is equal to (voltage applied across the heater) x (current flowing through the heater )x ( the time period for which the current flows) on putting the values as 220 volt x 15 ampere x 60 second we get the answer as 198 kilojoules
