AC Voltage generation

Sinusoidal Waveform

A representation of one cycle of alternating voltage or current, characterized by a smooth periodic oscillation.

Electromotive Force (EMF)

The voltage generated by a source such as a battery or generator, measured in volts.

Fleming's Right Hand Rule

A method used to determine the direction of current flow in a conductor when the motion and magnetic field polarity are known.

Phase Angle (Φ)

The angle in degrees or radians that a sinusoidal waveform has shifted from a reference point along the horizontal axis.

Frequency (f)

The number of cycles per second in a periodic signal, often measured in hertz (Hz).

EMF Induced Formula

The induced EMF in a single loop AC generator is calculated using e = E sinΦ.

Peak Value (E)

The maximum voltage or current value in an AC waveform.

Phase Shift

The difference in phase between two waveforms, often expressed in degrees.

Sine Function

A mathematical function that describes the relationship between the angle and the ratio of the opposite side to the hypotenuse in a right triangle.

Angle of Phase for EMF Calculation

The angle at which the induced EMF is measured in relation to the waveform, important for calculating values in AC generators.
