The necessary current, often referred to as the "required current," is the amount of electrical current needed for a circuit or device to operate effectively. It varies based on the specifications of the device, including its resistance and power requirements, which can be calculated using Ohm's Law (I = V/R). Ensuring the correct necessary current is crucial for optimal performance and to prevent damage to the device or circuit.

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.
No, the current will not flow in a circuit with a gap between two wires, as a complete circuit is necessary for current to flow. The gap creates an open circuit, preventing electrons from moving through the circuit. Current requires a continuous path to travel, and without that connection, there is no flow.
Excitation current in a generator refers to the current supplied to the rotor windings to create a magnetic field necessary for generating electricity. This current is crucial for controlling the voltage output and overall performance of the generator. By adjusting the excitation current, operators can regulate the generator's voltage and ensure stable operation under varying load conditions.
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
