In addition to the ammeter can measure the size of the current, what other purposes?

It is used to measure the current. Of course, the direction can also be measured. If it is connected with some sensors, it can also measure the temperature, pressure and other physical quantities

What's the function of ammeter besides measuring current?
nothing

It can also test whether there is current in the circuit. It can also be used as a wire in the school experiment. It can be connected to two sections of the battery with unknown positive and negative poles to judge the positive and negative poles, and so on

How to measure the current of the current meter

The commonly used ammeter is refitted from the small range ammeter g (meter head). The commonly used meter head is mainly composed of a permanent magnet and a rotatable coil placed in the magnetic field of the permanent magnet. When there is current in the coil, the coil deflects with the pointer under the magnetic force. The larger the current is, the greater the deflection angle of the pointer is, The current value through the meter can be read out by the position indicated by the pointer on the dial marked with current value
Connected in series to the circuit to be measured, the current should flow from the positive terminal to the negative terminal, because the internal resistance of the ammeter is very small, so it can not be directly connected to the two poles of the power supply without using electrical appliances

Why can ammeter measure temperature?

The resistance varies with temperature
