electrical shunt
An electrical shunt is connected in parallel with the ammeter to measure high current.
Noun: A low-resistance conductor connected in parallel with another device or component in an electrical circuit. Its primary function is to provide an alternative path for a portion of the electric current, thereby diverting it away from the main device.
The term "electrical shunt" is used to describe a specific component in electrical and electronic engineering. It is placed in parallel to measure current, protect equipment, or create a known voltage drop. * A common application is in ammeters, where the electrical shunt allows most of the circuit current to bypass the meter's sensitive movement. * To measure a very large current, an electrical shunt with a precisely known, very low resistance is used.
- Noun:
- The technician installed an electrical shunt across the terminals to safely measure the high current.
- The accuracy of the current reading depends on the precise resistance value of the electrical shunt.
- In this protective circuit, the electrical shunt diverts excess current away from the sensitive transistor.
- "to shunt current": This verb phrase describes the action performed by the shunt. While "electrical shunt" is a noun, the related verb "to shunt" means to divert or turn aside.
- The purpose of the component is to shunt a measurable portion of the total current.
- Shunt (Noun): In technical contexts, "shunt" is often used as a shortened form of "electrical shunt."
- A current-measuring shunt.
- Shunt Resistor: A more descriptive term specifying the shunt's function as a resistor.
- The voltage across the shunt resistor is proportional to the current.
- Bypass: (Noun/Verb) A path or component that provides an alternative route for a flow. While similar in function, "bypass" is a more general engineering term.
- Current Divider: A descriptive term for the circuit element's function.
- Shunt Wound: A term used in direct-current motors and generators, describing a field winding connected in parallel (shunt) with the armature.
- A shunt-wound DC motor.
An electrical shunt is connected in parallel with the ammeter to measure high current.
- a conductor having low resistance in parallel with another device to divert a fraction of the current
