    Calculate emf and internal resistance with two circuits with the same cell

    Thank you for the reply. I'm doing AS physics and I haven't heard of Kirchhoff's law before. Which equation would I use?

    Calculate emf and internal resistance with two circuits with the same cell

    Homework Statement A cell is connected to a 10.0 Ohm resistor. The pd across the 10.0 Ohm resistor is 10.43 V. A 4.00 Ohm resistor is connected in parallel with the 10.0 Ohm resistor. The pd across the 10.0 Ohm resistor falls to 7.87 V. Calculate the emf and the internal resistance of the...
