A battery of emf 12V having negligible internal resistance is connected to a single resistor of resistance 10Ω.
a. (i) Calculate the current through the resistor.
b. (ii) Determine the power converted to heat in the resistor.
c. (iii) The circuit is kept on for 5 minutes. Find the electrical energy converted to heat during this interval, expressing your answer in joules and in kilowatt–hours.
