This question is in two parts

The plates in (c) are replaced by a cell that has an emf of 12.0 V and internal resistance $5.00 \Omega$ . A resistor of resistance R is connected in series with the cell. The energy transferred by the cell to an electron as it moves through the resistor is $1.44 \times 10^{-18} \mathrm{~J}$ .

Define resistance of a resistor.

ratio potential difference/voltage (across resistor) to current (in resistor) / $\frac{V}{I}$
