What is shunt and multiplier in a volt-ammeter measuring instrument?
Wiki User
∙ 10y ago
shunt resistance is connected in parallel across an ammeter as a current sensor that is used to carry full current which would had otherwise pass through the instrument there by saving it from possible destruction.
while, a multiplier on the other hand connected in series with the voltmeter to serve as a voltage sensor for carrying full voltage and allowing just a fraction of the voltage to pass through the instrument saving it from destruction.

When measuring a large current flow should you use a shunt with zero resistance?
It is not a shunt with zero resistance. It is very small, but it is not zero. The large current develops a small voltage across the small resistance. Measuring that small voltage gives you a proportional measurement of the current.
What are the disadvantages of shunt for measuring high current?
When shunts are used in high current measurements, that actual current reading is "extrapolated"(multiplied by a factor then expressed) and variances in shunt tolerance may cause mistaken and less than accurate measurements.
What is a ventriculoperitoneal shunt?
When a shunt drains to the abdomen
What is shunt in electrical engineering?
In electrical engineering, shunt means 'parallel'.
How is a shunt coil installed?
'Shunt' is an archaic term, meaning 'in parallel with'. So a 'shunt coil' is connected 'in parallel' with... With what, of course, depends upon what sort of device you are talking about. For example the field coil of a d.c. shunt-connected motor has its field winding connected in parallel ('shunt') with the supply.
How measuring amps?
A; By using a voltmeter across a small shunt resistor

What instrument is used to measure amperage?
A: it is actually a meter that reads voltage caused by current flow. Basically any voltmeter can measure current flow by measuring the voltage drop across a very small [in value ] shunt Resistance's AC the current can be measured by induction on a coil

What are the differences of Long shunt vs short shunt generator?
In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
How do you use shunt in a sentence?
The word 'shunt' is both a noun (shunt, shunts) and a verb (shunt, shunts, shunting, shunted).Examples:He had to have a heart shunt put in. (noun)The engineer will shunt the train onto that track instead. (verb)

1.physiological shunt?
physiological shunt.
How do you measure DC current?
A: By introducing a very small shunt resistance in series with the source and measuring the voltage drop which a meter will translate into current

What is called when a child has value shunt caused of water in the brain?
The shunt used for a person who has hydrocephalus ("water on the brain") is not called a "value shunt". It is usually called a "ventriculo-peritoneal shunt" or "VP shunt" for short. Sometimes a "ventriculo-atrial shunt" or "VA shunt" is used instead.
Is shunt a Medical Term?
Yes, shunt CAN be a medical term.
