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.

What type of transformer connection can be used when it is necessary to rectify alternating current into direct current with a minimum of ripple?

bride transformer


What is exciting current in 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.


What is purpose of demagnetizing test during current transformer test?

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.


Will the current flow in a circuit in which there is a gap between two wires?

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.


What is meant by the term excertation current when refering to generator?

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.

What condition are necessary for a current to be present in a circuit?

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.


Is a conductor necessary for electricity to flow?

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.

Was the current Iraq War necessary?

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.


When a multimeter is set to measure resistance?

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
