What is the effect of low impedance transformer on regulation?
The lower the impedance, the lower the voltage drop across the transformer as it is loaded. This means regulation is better, since voltage variance is smaller.
What is magneto optic current transformer?
moct is device measure the current by means of faraday's effect..
How can an ammeter be connected in a circuit and not effect the flow of current?
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
What happens to other lamps in a parallel circuit if one lamp burns out?
If one lamp in a parallel circuit burns out, the other lamps are unaffected because current still flows through them. Total current in the system is reduced by the loss of the burned out lamp, which will raise voltage ever so slightly. That will have the effect of brightening the other lamps, but that effect is inconsequential unless there is significant impedance in the source or in the path to the lamps.
What is the affect of a series circuit on current?
by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese. Ans 2 . the current in series circuit of constant resistance will always be the same . It will not effect the current .
What is the effect of transformer impedance on short circuit current?
Short circuit current will increase a lot.

How does the loading effect of an ammeter in a low resistance circuit compare to the loading effect in a high resistance circuit?
The voltmeter has an internal resistance, which should be as high as possible. As this resistance draws current from the circuit under test, it will affect circuit operation. This is more pronounced in a high impedance circuit because the current drawn flows through higher resistances.
If impedance of power transformer is increase from 8 to 10 percentage then what will effect?
if the designed value of percentage impedance is change, for general this should affect tow things * if the percentage impedance is decrease this should increase the fualt level current *if the percentage impedance is increase this should increase the transformer losses and tempreture rise so the designed value of percentage impedance is determined according IEC if it is less than or equal 10% the margin should be + or_ 15%, if it is more than 10% the margin should be + or _ 15% so the percentage impedance of this transformer is not accepted according IEC standers
How you can eliminate loading effect in amplifiers?
By increasing the input impedance of amplifier.
What was the effect on the input impedance of lowering the operating frequency?
The input impedance should increase slightly for the lower frequency, when using a capacitive circuit.

What is input impedance of a circuit?
Impedance is the total opposition to current flow. It includes both resistance AND reactance (capacitive and inductive). Impedance varies with frequency, while plain resistance does not. Scroll down to related links and look at: "Different names for the two impedances Z1 and Z2" "Calculation the damping of impedance bridging or power matching an interface connecting Zout and Zin" "Impedance bridging or voltage bridging of two audio units".
How you can minimize the loading effect on voltmeter?
Loading refers to the phenomena that occurs when a load circuit having low effective impedance is connected to a supply circuit having higher effective impedance.
The opposition to the flow of electrons through a conductor?
In the simplest case, that would be resistance - but there is also another type of opposition (only relevant for AC) called reactance. The combined effect of resistance and reactance is called impedance.
What is the effect on the current when a short circuit occurs?
The current increases.
