What factors determine the induced voltage of a dc machine?
i think that it is possible that for unknown circumstances i don't know it.
When a magnetic field and a wire are moved near each other the voltage produced is said to be?
Induced.
How single point grounding reduces ground loop?
A voltage can be induced on a ground wire by other wires nearby. If you have more than one ground wire, The induced voltage will cause a current flow up one, and down through the other. By removing one of the two, you interrupt the loop.
What four factors determine the amount of resistance in a circuit?
Material that makes up the wire, length of wire, diameter of wire, and temperature of wire
True or false an electromagnet must include a coil of wire?
A magnetic field is induced by pushing current though a wire; so you could consider a straight wire an electromagnet. Using more coils will strenghten the electromagnet, though, so a straight wire version will be very weak comparitively.
For voltage to be induced from one stationary wire to another one wire must have what type of flow?
for uhmm voltage?:)

What factors determine the magnitude of induced current in a wire loop when exposed to a changing magnetic field?
The magnitude of induced current in a wire loop when exposed to a changing magnetic field is determined by factors such as the strength of the magnetic field, the rate of change of the magnetic field, the number of turns in the wire loop, and the resistance of the wire.
What is difference between induced voltage and induced current?
Just as a current flowing through a wire will produce a magnetic field, so a wire moving through a magnetic field will have a current flowing through it. This is called electromagnetic induction and the current in the wire is called induced current. A stationary wire in the presence of a changing magnetic field also has an induced current. A changing magnetic field can be produced either by moving a magnet near to the stationary wire or by using alternating current. A stationary wire in a magnetic field which is not changing will have no current induced in it. You will sometimes see this effect described as induced voltage. Strictly speaking, you will only get an induced current in the wire if it is part of a complete circuit. A wire which is unconnected at both ends will have a difference in voltage between the ends (a potential difference) but current can only flow when the wire is in a circuit. Induced current is used in electricity generation and transformers.Another AnswerThere is no such thing as an 'induced current', only an 'induced voltage'. Current will flow only if the conductor into which the voltage is induced forms part of a closed circuit.
How is induced current in a wire generated and what factors influence its strength?
Induced current in a wire is generated when there is a change in magnetic field around the wire. Factors that influence the strength of the induced current include the rate of change of the magnetic field, the number of turns in the wire, and the material of the wire.
What would induce a greater electric current in a wire?
A greater electric current in a wire can be induced by increasing the voltage applied across the wire or decreasing the resistance of the wire. Both factors contribute to Ohm's Law (V=IR), where V is voltage, I is current, and R is resistance. Increasing the voltage or decreasing the resistance will lead to a higher current flowing through the wire.
For voltage to be induced from one stationary wire to another one wire must have a n what type of current flow?
Intermittent. Faraday's law tells us that voltage can only be induced in a second coil when the current in the first coil changes
How do you determine which wire is the 'feed' wire?
Check it with a voltmeter or with a voltage detector.
When a magnetic field and a wire are moved near each other the voltage produced is said to be?
Induced.
What are the three ways in which voltage can be induced in a wire?
Voltage can never be induced in a straight open wire because flux through a wire is zero but a coil made up of a wire can have induced voltage. Methods Move a magnet to and fro through the coil, the magnitude can be changed by altering the relative velocities between them Move the coil relative to he still magnet Place the coil in a time varying magnetic field such that the flux linked through the coil changes with respect to time Place the coil tn an uniform magnetic field and alter its area with respect to time
If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
How was current produce or induced?
Current can be induced in a conductor through electromagnetic induction, where a changing magnetic field causes a flow of electric current. This can be achieved by moving a magnet near a conductor or by varying the current in one nearby. Alternatively, current can be produced by a voltage source such as a battery or generator that creates a potential difference to drive the flow of electrons.
