Question

what is an electric circuit? how should an ammeter and voltmeter connected in a circuit​

Answer 1

An electric circuit is a path in which electrons from a voltage or current source flow Myof electrons. The point where the electrons leave an electrical circuit is called the "return" or "earth ground". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit.

An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.
