already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

Alternating voltage is the E.M.F. and is one whose magnitude whose magnitude changes with time and direction reverses periodically.
The instantaneous value is given by
E=Eo sin w t, where,E=value of alternating voltage at time t
Eo = maximum value of alternating voltage(amplitude)
w=angular frequency of supply.

Why is alternating current low voltage?

Alternating current is not necessairly low voltage, on the controrary AC is more oftenly used for when high voltage is needed. Most power distribution systems (extremely high

How do you control dc voltage in alternators?

Typically by varying the magnetic field strength. This is done by varying the current flow through the field windings.. It is usually accomplished by a voltage regulator circ

Why it is called alternating current and not alternating voltage?

Although in AC, the voltage does change, it is the reversing of direction of flow of the current which was used to designate the AC name. Answer In engineering termin

What is average value in alternate voltage?

The term is 'alternating voltage', not 'alternate voltage'. For an a.c. voltage or current, the average value is taken over half its wavelength because, over a complete wave

What is the RMS value of an alternating voltage?

The RMS value of an sinusoidal alternating voltage is 0.707 of the peak value. That is one half of the square root of two. The r.m.s. value of any alternating current or

Why it is called alternating current not alternating voltage?

There's absolutely nothing wrong with using the term 'alternating voltage', if you are describing voltage rather than current. However, In engineering terminology, the abbrevi

What changes the voltage of an alternating current?

When a conductor passes through, or 'cuts', a magnetic field, a voltage is induced into that wire. The magnitude of that voltage is proportional to the sine of the angle at wh

What is the reason if alternator does not give the voltages?

If the alternator is installed on or intended for a particular vehicle, the voltage would be the battery voltage of the vehicle. Generally this would be 12 V for most modern c

How do you check the voltage on an internal alternator?

Internal or external regulator doesn't matter. you can see if it's putting out by running a voltmeter across batt terminals with car running also if it runs with batt disconne

How do you increase output voltage of a alternator?

The voltage output is controlled by the voltage regulator. Check to see if you are getting a DC field voltage. On the voltage regulator there are terminals to different pieces
