Question

The magnitude of Alternating Current (AC):

पर्याय

• Remains generally constant

• Decreases exponentially to zero

• Varies sinusoidally with time

• Increases linearly with time

Answer 1

The magnitude of AC varies sinusoidally with time and is expressed as \[i = I_m \sin(\omega t)\]. In contrast, ideal DC has a generally constant magnitude, expressed simply as \[I = \text{constant}\].
