We know the potential difference across and the current through it, so we can use ohm's law to calculate the value for the resistance: The equivalent resistance of the circuit is (since the load resistance is in series with the internal resistance), so the current flowing in the circuit is given by (145) the power output of the emf. Can i assume the internal resistance as a resistor before or after.
