Why alternating current is represented by sinusoidal wave form?

Answer 1

AC voltage, like the voltage in your house, is typically referred to as 120vAC. This means the voltage swings 120V positive and 120V negative 60 times per second (60 Hz) 360 degrees total (sine wave). Current and voltage go hand-n-hand so the current alternates with the voltage. the RMS value is what we experience at the output (160vAC is actually sent to the circuits)

Answer 2

Because if you could draw a graph of the voltage at a single point as time goes on,

or a graph of the current flowing past a single point as time goes on, both graphs

would have sinusoidal waveforms.

Answer 3

I am confused with this question...may be more details...because alternating current is not exactly sinusoidal

Answer 4

A sinusoidal voltage is an oscillating voltage that can be described mathematically through the use of a sine function.
