bride transformer
Excitation current is the current necessary to "turn on" the transformer so it can be used. It's energy that is lost in the use of the transformer. Most of this loss I believe is associated with the hysterisis loop, although some will be lost as eddy currents.
The residual magnetisation present in the current transformer coils may cause the errors during measurement of high currents. So that it is necessary to check that.
It is not necessary for anything about them to be the same.All that is necessary is that they create the desired equivalent resistor, having the correct resistance and power dissipation rating without overstressing either resistor.
A load with a low power factor draws more load current than necessary, so the supply conductors need to have a greater cross-sectional area than would otherwise be necessary.
So that you know what current it takes and what current it leaves.

The only two things needed for current flow are electromotive force or voltage and a conductor. The amount of current flow will depend on the "Resistance" in the circuit.
Yes, a conductor is necessary for electricity to flow. Conductors are materials that allow the flow of electric current, while insulators do not allow the flow of electric current.

A difference of potential (which is measured in Volts) is needed to make current flow.
some resistance and potential difference
No, it is not necessary.
The keyword "fmm no longer required" is no longer necessary in the current system because the system has been updated to function without needing that specific keyword for its operations.

No. The Iraq War was not necessary for the United States to be safe and secure. Iraq, although a regional problem, was not a threat to the United States.
it determines how well the current flows through the wires. ANSWER: When there is no outside power connected to it. But some power is necessary to read the resistance so the meter battery will supply the current necessary to measure the IR drop and translate that to resistance
