4. An electric immersion heater normally takes 100 minutes to bring cold water in insulated container to a certain temperature, after which a thermostat swi heater off. One day the line voltage is reduced by 60% because of overload does the heating of water take now? Assume that the resistance of the heat does not change. switches th How long
