A rechargeable battery has an emf of 13.2 V and an internal resistance of 0.850 . It is charged by a 14.7-V power supply for a time interval of 1.80 h.

Why is the following situation impossible? A technician is testing a circuit that contains a resistance R. He realizes that a better design for the circuit would include a resistance 73R rather than R. He has three additional resistors, each with resistance R. By combining these additional resistors in a certain combination that is then placed in series with the original resistor, he achieves the desired resistance.
