Attached to the DC meter - shunt
Description: Attached to the dc meter - shunt, which is actually a precise resistance, is usually used when measuring high current.When the current flows through the shunt, a millivolt voltage will appear at both ends of the shunt. The millivolt voltmeter will be used to measure the voltage, and the voltage will be converted into the current to measure the large current. Due to the Joule’s law, the shunt will generate serious heat under the action of the current, so it needs to have a small temperature coefficient and power coefficient to ensure the stability of the resistance value.
