Explanation:
Detailed explanation-1: -Often voltage is seen to only exist when there is a current in the circuit/device; sometimes voltage is even seen as caused by current. A very small number of students are likely to have the idea that voltage is what is ‘used up’ in a circuit (in, for example, a light globe).
Detailed explanation-2: -Voltage is sometimes described as the ‘push’ or ‘force’ of the electricity, it isn’t really a force but this may help you to imagine what is happening. It is possible to have voltage without current, but current cannot flow without voltage.
