Connected in parallel with the system to reduce overcurrent/losses
An AC (non-polarized), usually high voltage capacitor that is connected in
parallel with an inductive Motor (and very close to the motor, or other
inductive load) to help reduce Reactive Power (Magnetizing AMPS)
which do no real work but only cause extra heat in the wiring and motor
as there is a Lagging Current Phase Angle created by an Inductor and a
Leading Current Phase Angle created by a capacitor which helps correct
the impedance mismatch between line and load.
Google "Reactive Power" and/or "ELI ICE man" for more information.

What is the Difference between shunt capacitor and shunt reactor?
One is a capacitor and one is a reactor. Shunted capacitors are used to raise th voltage in the power system, while shunt reactors are used to lower it. Capacitors are typically installed close to load because of this; reactors are typically on very high power lines where the capacitance of the power line can cause severe overvoltages when loading is light, and at large generating stations.
What is amplifier roll off?
A practical amplifier will contain several components of a "shunt" capacitance inherent in the transistor and physical wiring of the amplifier circuit. As the frequency of the input signal increases, the reactance of these shunt-capacitances will decrease until, at a frequency determined by the value of the shunt-capacitance and the circuit impedance, signal attenuation begins to take place. Thus the shunt capacitances limit the high-frequency response of the amplifier (note that the transistor itself also has inherent limits to it's high frequency amplifying capability). In the case of operational amplifiers, many operational amplifiers are internally compensated by a small capacitor (e.g. about 30pf for a 741). The internal frequency compensation capacitor prevents the operational amplifier from oscillating with resistive feedback.
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.
What are the advantages and disadvantages of pi section filter over a shunt capacitor filter?
1.More output voltage compared to shunt capacitor filter. 2.Less No of ripples. 1.Higher cost relative to shunt capacitor filter. 2.Larger in size.
What is the function of a bypass capacitor in an amplifier?
Bypass capacitors are used to bypass (shunt) unwanted signals to the ground. A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
Why do you find out capacitor before shunt resistor?
I need answer of this question plz as soon as possible
What is the effect of shunt capacitor?
A shunt capacitor creates a low resistance path in a circuit so that electricity can pass around to another point. Shunt capacitors create shorts when they receive abnormally high amounts of voltage to correct series circuits.
Capacitors block......... frequencies filling the blank?
It depends on whether the capacitor is series or shunt. If series, capacitors block low frequencies. If shunt, capacitors block high frequencies.
What is purpose of emmiter bypass capacitor in R-C coupled amplifier?
Emitter bypass capacitor is a capacitor which provide low impedance to AC and high impedance to DC . AC is shunt then only DC appears on RC and volage gain increses.
What is the Difference between shunt capacitor and shunt reactor?

When capacitors are used to shunt current across components such as resistors they are called?
A capacitor is typically placed across a resistor for the purpose of shunting either the AC component of a current (as in a transistor amplifier) or transient AC 'spikes', and is referred to as a "bypass capacitor".
How does a shunt trip relay work?
A shunt capacitor creates a low resistance path in a circuit so that electricity can pass around to another point. Shunt capacitors create shorts when they receive abnormally high amounts of voltage to correct series circuits.

Why thermocouple voltmeter is connected across shunt resistance and electronic voltmeter across capacitor?
There is no such a thing as a thermocouple volt meter. A analogue or digital millivolt meter or volt meter is connected across a shunt or parallel with the shunt to measure the current through the resistor. Say the resistor value = 1 Ohm, then by using the Ohm law formula to calculate the current, say the voltage (voltage drop), read on the volt meter is 1.5 Volt that is R*V = A that is, 1Ω*1.5V = 1.5 Amp. Any type of DC volt meter, analogue or digital can be used to measure the voltage across a capacitor if the value of the capacitor is large enough that reading will be true RMS. as long as the supply current (EMF Power) are larger than the load current.
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.
