1. The no-load terminal voltage of a battery is 30 V. The terminal voltage drops to 22 V when supplying a current of 5 A. Determine the emf and the internal resistance of this battery. 2. Two identical zinc carbon batteries are available. When connected in series, they supply 0.5 A to a 4 ohm resistor. When connected in parallel, they supply 0.4 A to a 5 ohm resistor. Determine the emf and internal resistance of each battery. 3. When supplying a current of 5 A, the terminal voltage of a battery is 15 V. The battery is then recharged at a rate of 3 A and the terminal voltage is found to be 21 V. Determine the emf and the internal resistance of the battery. 4. A battery with an emf of 12 V and an internal resistance of 0.8 ohm is to be recharged through a 20 V source. (a) show by means of a diagram the connection of the circuit elements. (b) What is the current in the circuit? (c) The recharging current is to be limited to 3 A. What is the value of the limiting…
