# What is a current meter?

Also known as an ammeter, a current meter measures the flow of electricity in a circuit.

A current meter, commonly known as an ammeter, is a device that measures the flow of electrical current in a circuit. Current meters can be digital or analog and are often part of a larger multimeter that can measure voltage and resistance as well. These devices—both current and multimeters—are typically rectangular and box-shaped, with a digital display or analog meter, multiple dials or switches, and a red and a black wire coming out of it.

Current meters can help electricians find out if there is a problem with an electrical device.

When referring to electricity, current is the action of electrical charge or electrons flowing through the wires that make up a circuit. The rate of current movement can be measured using a meter. Current flows in one direction, usually from positive to negative, and it needs to flow in a circuit, which is like a continuous loop. It flows more easily through some materials, such as metal wire, than others. Wood, for example, does not conduct electricity at all.

Electrical current is measured in a unit called amperes, abbreviated as “amps” or simply “A”, using a current meter. When measuring current, the meter is actually measuring how many electrons pass a specific point every second. In order for current to be measured, it must flow through the meter, which is done by making the current meter part of the circuit.

The meter has two wires coming out of it, with probes or clamps attached to the ends that connect to the circuit. To do this, the circuit needs to be broken at the place where the current will be measured, so the red wire is clamped or tapped on the side of the wire that leads back to the positive end of the power supply, and the black wire is connected to the side. negative. Once the meter is placed into the circuit in this way, it will take a reading.
