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 else can I help you with?
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.
Explain why a series resistor is necessary when a diode is forward-biased?
A series resistor is necessary when a diode is forward-biased to limit the current flowing through the diode. Without this resistor, the current can increase rapidly due to the diode's low forward voltage drop, potentially exceeding the diode's maximum current rating and causing it to overheat or fail. The resistor helps ensure that the current remains within safe operating limits, thereby protecting the diode and ensuring reliable circuit operation.
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.
Why tranformer rating is necessary?
So that you know what current it takes and what current it leaves.
Why potential difference is necessary for the flow of current?
fu
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.
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 necessary in order to push current through a conductor?
A difference of potential (which is measured in Volts) is needed to make current flow.
What conditions are necessary for a current to be present in a circuit?
some resistance and potential difference
Does the current periodic table make use of quantum mechanics model?
No, it is not necessary.
Why is the keyword "fmm no longer required" no longer necessary in the current system?
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.
What are the names of the 2 ions necessary to create an electric current in a nerve fiber?
potassium
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
