A secondary cell having an end of 2v and internal resistance of 1amp is connected on series with a primary cell having an end of 1.5v and internal resistance of 100amp, the negative terminal of each cell being connected to the positive terminal of the other cell . A voltmeter having a resistance of 50amp is connected to measure the terminal voltage of the cells. Calculate the voltmeter reading and the current in each cell.
