Shunt Resistor Circuit. It is connected in parallel with the ammeter whose range is to be extended. This means that the current is equal to the voltage divided over the resistance or.
A shunt resistor is a precision device used to measure current in an electrical circuit. Shunt resistors have a maximum current rating. The origin of the term is in the verb to shunt meaning to turn away or follow a different path.
It is connected in parallel with the ammeter whose range is to be extended.
This means that the current is equal to the voltage divided over the resistance or. Also known as a current shunt or an ammeter shunt it works by measuring the voltage drop across a known resistance. Shunt resistors do the same thing and create a very low resistance path for the current to pass from one circuit portion to another circuit portion. I v r 0 030 0 001 30 a.
