As an introduction to the next chapter, this figure shows that the term "shunt resistor" should be understood in the context of what it shunts. In this example the resistor RL would be understood as "the shunt resistor" (to the load L), because this resistor would pass current around the load L. RL is connected in parallel … See more In electronics, a shunt is a device that creates a low-resistance path for electric current, to allow it to pass around another point in the circuit. The origin of the term is in the verb 'to shunt' meaning to turn away or follow a different … See more In photovoltaics, the term is widely used to describe an unwanted short circuit between the front and back surface contacts of a solar cell, usually caused by wafer damage. See more Capacitors are used as shunts to redirect high-frequency noise to ground before it can propagate to the load or other circuit components. See more Where devices are vulnerable to reverse polarity of a signal or power supply, a diode may be used to protect the circuit.
