Question

A steady current of 0.5 A flows through a wire. How much charge passes through it in one hour? A storage battery of internal resistance of 0.4 2 is to be charged from a DC line. If the EMF of the battery is 12 V, what resistance must be placed in series with the battery to limit the charging current to a safe value of 4 A? What is the TPD? A 200-W heating appliance uses a current drawn from a 110-V line. (a) What is the resistance of the heater? (b) Find the number of calories generated in one hour.
