How alternating voltage is generated in a coil of wire when it is rotated between the poles of a magnet?
Electical current.
=============================
Answer #2:
When a coil moves in the vicinity of a magnet, a voltage between the ends
of the coil is produced. If the coil happens to be part of a closed circuit, then
there could be an electrical current.
Answer #3
When a coil moves through a changing magnetic field, a voltage is produced, and when a resistor is connected to the coil some current flows and power is produced in the resistor. This power comes from the mechanical power needed to push the coil through the magnetic field when it carries a current.

What is alternating quantity?
An alternating quantity is a type of electrical current or voltage that periodically changes direction, moving back and forth. It is commonly represented as a sinusoidal waveform that alternates between positive and negative values. This type of electricity is used in household appliances and is generated by power plants.
Does vac stand for volt amp current or volt alternating current?
Vac usually stands for voltage alternating current. It represents the voltage of an alternating current electrical system.
What is Alternating current is measured in?
Alternating Current is measured in Amperes.
What is term used when an Alternating current acts like a direct current?
Perhaps you are asking how the voltage of alternating current is measured, to be equivalent to the voltage of a direct current system. Alternating current and direct current have distinct properties. With direct current, voltage is at a constant polarity, and a direct current voltage source will maintain a uniform, constant voltage level. Alternating current reverses polarity at a given frequency and therefore it's voltage continuously varies from a positive peak voltage level, through zero, to a negative peak voltage level, repeating this cycle continuously. For this reason, voltage of an alternating current system, is measured in root-mean-square (rms), which is a voltage, which when multiplied by the current in amperes, calculates power which is equivalent to that of direct current of the same voltage and current values. With a typical sinusoidal waveform, the peak voltage of alternating current is divided by the square root of 2 to determine the rms voltage. The 120 volts output in the wall outlet in our home is actually about 170 peak volts.
Which apparatus changes a direct current to alternating current?
An inverter is the apparatus that changes direct current (DC) to alternating current (AC). It does this by converting the fixed voltage and direction of DC electricity into an oscillating voltage and alternating direction of AC electricity.
How is alternating current (AC) generated?
Alternating current (AC) is generated by rotating a coil of wire within a magnetic field, which induces an alternating voltage in the coil. This process is known as electromagnetic induction and is the principle behind how AC electricity is produced in power plants.

What is the science behind the alternating current?
When a sinusoidal alternating voltage is applied in a circuit, the resulting alternating current is also sinusoidal and has the same frequency as that of applied voltage .However, there is generally a phase difference between the applied voltage and the resulting current.This is how alternating-current circuit works.

What is the name of the component that is used to increase or decrease alternating voltage?
A transformer is used to increase or decrease alternating voltage.
What condition will sinusoidal voltage be generated in a coil of wire that rotates in a magnetic field?
a generator or alternator,if the magnetic is permanent the current produced from the coil will be alternating current ac.
How do you derive alternating current from car alternator?
The car's alternator is a three phase generating system. Inside the alternator is a three phase full wave diode bridge that changes the AC generated voltage to a DC voltage.
When an alternating voltage is applied to purely resistive circuit what happens?
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
Does vac stand for volt amp current or volt alternating current?
Vac usually stands for voltage alternating current. It represents the voltage of an alternating current electrical system.
What is the Difference Between VAC and DC Current?
VAC is voltage of alternating current signalDC current is amperage of a direct current signalAnswerYour question contradicts itself, as the symbol, V,represents voltage, not current.However, V a.c., represents an alternating voltage -one in which the direction in which the voltage is acting continuously reverses itself. Vd.c. represents a direct voltage, in which the voltage continuously acts in the same direction.
What does a transformer do to a voltage in a power line?
A transformer is used to step up (increase) or step down (decrease) an alternating voltage with very little loss of energy.
What is the voltage of alternating current?
60 Hz
Relation between voltage speed and current in alternating current motor?
voltage is inversly proportional to speed speed and current are directly proportional to each other but voltage and current are directly proportional to each other..
