secondary cell having an e.m.f. of 2V and an internal resistance of 1 ohm is connected in series with a primary cell having an e.m.f. of 1.5V and an internal resistance of 100 ohm. The negative terminal of each cell is connected to the positive terminal of the other cell. A voltmeter having a resistance of 50 ohm is connected to measure the terminal voltage of the cells. Calculate the voltmeter reading and the current in each cell.
