A cell of emf E and internal resistance r was connected in series with two series external resistors A(8ohms) and B (2 ohms). A high resistance voltmeter connected across A was found to read 8 volts. When another resistor C(of 8 ohms) was connected parallel to A, and then across A and C, the voltmeter reads 6volts.
1. Draw the circuit diagram
2.Calculate the internal resistance of the cell
3.Calculate the emf of the cell
