V = I * R
or
I = ( V / R )
I = current (amps)
V = Voltage
R = Resistance
The current in a circuit depends on the applied voltage and the resistance of the circuit.

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.
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
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.
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 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 was current produce or induced?
Current is induced and not produced. when an electric wire is passed through magnetic field the current is induced in the electric wire, this electric wire is enamelled copper conductor of a rotor.AnswerCurrent is never 'induced' into a conductor. It is a voltage that is induced. If that conductor is then part of a complete circuit, then the induced voltage will cause a current to flow. The induced voltage will occur even when the conductor is open circuited.
Moving a magnet in and out of a coil of wire produces?
That will induce a voltage across 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.
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).
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
