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 amperes. The symbol for ampere is A. For example, ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

THIS communication is concerned with the measurement of the transmural potential difference, the short-circuit current, and the net sodium flux in isolated segments of rabbit ileum using a method ...
