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 device called an ammeter is used to measure current. Some types of ammeter have a pointer on a dial, but most modern ammeters have a digital display. To measure the current flowing through a ...

This circuit design for a current-mode analog multiplier/ divider is based on current-controlled conveyors (CCCII) and a second-generation current conveyor (CCII). No passive components are used.
