# Ohm's Law

In a circuit there is a single resistor, $R$, and a cell in series. $1.875 \times 10^{21}$ electrons pass a point P in the circuit every 50 seconds. The cell provides $4.8 \times 10^{-18}$ joules of energy to each electron. You can assume there is negligible internal resistance and it is an ideal circuit. Determine the resistance of resistor $R$ in ohms.
