Current is the rate at which charge is flowing. Resistance is a materialâs tendency to resist the flow of charge (current). So, when we talk about these values, weâre really describing the movement of charge, and thus, the behavior of electrons.
Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in units called amps. The symbol for amps is A. For example, 20A is a bigger current than 5A.
