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, ...

To improve efficiency in high-power applications, voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach ...

You need to know how to measure the current that flows through a component in a circuit and the voltage across it. The ammeter must be connected in series with the component – remember, in a series ...
