- Difference between current and voltage

a) an electric current is defined as the number of electrons passing at a given moment/second.

b) voltage is defined as difference of potential energy per unit of charge, between 2 points.

c) Without Voltage the electrons will pull randomly around the circuit. Voltage is the one pulling electrons from negative to positive

d) The total water that goes trough the pipes is the current and the total amount of water in reservoir is the voltage. The voltage will remain the same if there is no downfall pipe of water (9Volts).
