Problem P. 3803. (May 2005)

P. 3803. The heater filaments of an electric cooker are connected as is shown in the figure. If we connect voltage between points A and B we can boil 500 g of water in a certain time. How much water can be boiled during the same time if we put the voltage between points A and C? (Let us assume that the heater filaments only heat the water and the initial temperature of the water is the same in both cases.)
