sm people say theres Alternative Current pass through the kettle and the ans is B
dude alternating current does not mean that current is goin in both directions...
it means that negative is flowing that positive is flowing then negative then positive... +-+-+-+-.. like that always in one direction...
remember that + does not mean protons... they are always electrons both + and - ... they have been given that name + and - to clear the meaning of AC and DC current...
