A shunt is actually a resistance with very small resistance. When a direct current passes through it, a voltage drop is generated for the display of a direct current ammeter. The DC ammeter is actually a voltmeter with a full scale of 75mV. DC ammeter and shunt are used together. For example, the cu... read more
The shunt is used to measure the DC current. It is made according to the principle that the DC current produces voltage at both ends of the resistance when it passes through the resistance. It is made of insulating ceramics with uniformly distributed holes. The protective gas from the welding torch ... read more
