What is meter shunt?

A meter shunt is an electrical accessory that is used to divert or redirect a portion of the electrical current flowing through a circuit. It is a low-resistance resistor that is connected in parallel with an ammeter to measure large electrical currents. The meter shunt is designed to allow a small current to flow through the ammeter while the majority of the current is diverted through the shunt.

The meter shunt is commonly used in applications where high currents need to be measured accurately, such as in automotive and industrial applications. It helps to protect the ammeter from damage due to high current levels and ensures accurate measurement of the current flow.

The resistance of the meter shunt is carefully calibrated to ensure that the current flowing through the ammeter is proportional to the total current flowing through the circuit. This allows accurate measurement of high electrical currents without causing damage to the ammeter.

Overall, the meter shunt is a useful accessory for measuring high electrical currents accurately and safely.
