How is electric current measured using an ammeter?

Electric current is measured using an ammeter by connecting it in series with the circuit.

To measure electric current, an ammeter is connected in series with the circuit. This means that the current flows through the ammeter, allowing it to measure the amount of current passing through the circuit. The ammeter must be connected correctly, with the positive terminal connected to the positive end of the circuit and the negative terminal connected to the negative end of the circuit. If the ammeter is connected in parallel, it will create a short circuit and damage the ammeter and the circuit.

Ammeters are designed to have a very low resistance, so that they do not affect the circuit they are measuring. They are usually calibrated in amperes (A), which is the unit of electric current. To read the current, the ammeter must be read in series with the circuit. The reading on the ammeter will show the amount of current flowing through the circuit at that point in time.

It is important to note that ammeters should only be used to measure electric current, and not voltage or resistance. Attempting to measure voltage or resistance with an ammeter can damage the ammeter and the circuit. To measure voltage, a voltmeter should be used, and to measure resistance, an ohmmeter should be used.
