shunt circuit
Definition
Noun: A shunt circuit is an electrical circuit configuration where the current flow splits into two or more parallel paths before merging back together to complete the circuit. This design provides an alternative pathway for electrical current.
Usage
A shunt circuit is used to divert a portion of the current away from the main path. It is a fundamental concept in electronics and electrical engineering. - The ammeter was connected via a shunt circuit to allow measurement of high current. - Engineers designed a shunt circuit to protect the sensitive component from excessive current.
Advanced Usage
- In Instrumentation: A precision shunt resistor is often placed in a shunt circuit to measure large currents; the voltage drop across the known resistor is used to calculate the current.
- In Power Systems: Shunt circuits can be used for reactive power compensation or to create a specific voltage reference point.
Variants and Related Words
- Shunt (noun/verb): The act or component that provides the alternative path. (e.g., )
- Parallel Circuit: A broader term for a circuit where components are connected across common points, providing multiple paths. A shunt circuit is a specific type of parallel configuration.
Synonyms
- Bypass circuit
- Parallel branch
- Diverting circuit
Related Phrases
- To shunt current: The action of diverting current through an alternative path.
- The resistor will shunt most of the current away from the LED.
Noun
-
a closed circuit in which the current divides into two or more paths before recombining to complete the circuit
