The potential difference (V) can be calculated using the formula:
V=WQV=\frac{W}{Q}V=QW
where:
- WWW is the energy transferred (in joules),
- QQQ is the charge transferred (in coulombs).
Given W=20 JW=20,\text{J}W=20J and Q=8 CQ=8,\text{C}Q=8C,
V=20 J8 C=2.5 VV=\frac{20,\text{J}}{8,\text{C}}=2.5,\text{V}V=8C20J=2.5V
So, the potential difference is 2.5 volts.
