Problem

An electric kettle is connected to a 230 V230\,\text{V} mains supply and draws a steady current of 6 A6\,\text{A} for 15 min15\,\text{min}. Answer the following. (i) Calculate the total charge that passes through the kettle in this period. (ii) Determine the number of electrons corresponding to this charge. (iii) If the same amount of charge were to pass through the kettle in 5 min5\,\text{min} instead, find the constant current that would be required.
