To measure the current flowing through a component in a circuit, you must connect the ammeter in series with it. Remember, electric current is measured in amperes, or amps for short.

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.

This project demonstrates step-by-step instructions to measure current, voltage, and wattage with precision. Using simple components and coding, this circuit provides accurate readings ...

A great example is this simple wireless AC current detector from [NEW PEW]. The circuit is a simple one, and a classic. The spring from a ballpoint pen is soldered to the base of a BC547 ...

For measuring resistors in a circuit, though, you need a whopping six wires. This technique uses the two extra wires to control a balance voltage that keeps the current between the unknown ...

Passive components don’t need an external power source to function and only require the current traveling through the connected circuit. They either consume or store energy. A simple way to test ...
