Problem
A resistor of resistance 18Ω is connected to a battery that delivers a steady current of 0.75A. Answer the following:
(i) Calculate the electrical power developed in the resistor.
(ii) Determine the electrical energy converted into heat in the resistor in 10min.
(iii) If the current through the same resistor were doubled, calculate the new power and compare it with the power obtained in part (i).
