A) A mercury cell has an emf of 1.35 V and an internal resistance of 0.041 Ohm. If it is used in a circuit that draws 1.50 A, what will its terminal voltage be? B) What is the resistance of a resistor it a potential difference of 36 V between its ends results in a current of 1.20 mA? C) What is the potential difference (voltage) between the ends of a resistor if 24.0 J of work must be done to drive 0.30 C of charge through the resistor?
