A shunt resistor is used to carry a majority of the electrical current away from the outlet. This causes the risks of electric shock to be down significantly, but still not completely gone.

Why you use 250 Ohm resistor in series with HART protocol communication?
You need to use the 250 Ohm resistor in series with HART protocol communication because it acts as a shunt resistor.
How do you calculated the current shunt?
Write down the Ohm's law expression of "V = I * R" where "V" is the voltage drop across shunt resistor, "I" is the current flowing through shunt and "R" is the shunt resistance.Substitute value of voltage "V" and current "I" in the Ohm's law expression. For example, if voltage across shunt is 10 volts and current flowing through it is 1 ampere, then the expression is 10 = 100 * R.Divide the expression throughout by 100 to calculate the "R" value. Using a calculator, find the value of "R." From the example, the value of "R" will be 0.1 ohm, which is the value of shunt resistor.
How shunt generators used in electroplating?
A shunt generator is used to provide electrons (electrical energy) to the electroplating machine.
What is described as a device with specific resistance and is used to control current?
A current shunt is a device with a very low resistance, usually around one ohm. The exact resistance of the shunt is printed on the device for reference, and it is often slightly higher or lower than nominal, for example a 1 ohm shunt may actually have a resistance of .99986 ohms or 1.0002 ohms. A current shunt is not used to control current, however, so I do not know if this is the device you are asking about. It is used to measure current by using a precision voltmeter to measure the voltage drop across the shunt, and then using ohms law to calculate the current. Voltage (Volts) divided by Resistance (Ohms) equals Current (Amps). When the shunt is placed so that it interrupts a circuit, (placed in series), the current flowing in the circuit can be accurately measured with the shunt, without changing the values in the circuit enough to affect it. Many shunts of this type have a large heavy duty resistor that does not overheat easily. The shunt should also have a max current rating listed on it.
What are the functions of shunt trip coil in ACB?
shunt trip coil used to trip the breaker automatically or manually.
Do you need to put a shunt resistor to connect the ac voltmetr?
Shunt resistors are used with ammeters; voltmeters require series resistors.
Which has a highest resistance between shunt resistor and series resistor?
If you are placing more than one resistors in series, then its combined resistance is higher than when you place these resistors in shunt.
How measuring amps?
A; By using a voltmeter across a small shunt resistor
Is shunt a bypass resistance?
It is the resistance across the cell to invoke a constant draw. This makes the cell work efficiently under ideal conditions. To do it properly new cell management systems measure the temp. and voltage output and put a load on the cell that makes it work best.
Why wouldn't the shunt resistor in the ammeter protect the ammeter when the ammeter is connected in parallel?
Connecting an ammeter in parallel subjects that ammeter to the full supply voltage. The shunt resistor is not designed to sustain that value of voltage and will burn out. Also, the clue is in the word 'shunt' (which means 'in parallel') which means that the coil will also burn out!
Why do you find out capacitor before shunt resistor?

How you convert galvanometer into ammeter in detail?
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
What does a shunt resistor across the base tank coil of a linear amplifier do?
If the shuntresistor should open, the diodes will forward bias
What is shund resistant its usage in electrical?
A shunt resistor passes current in parallel with a lower current device. It was used in analog meters to allow a 50 microamp meter to directly read 10 amps.
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.
