Question

Which of the following is the example expression for Alternating Current?

पर्याय

• \[I = \frac{Q}{t}\]

• \[i = I_m \sin(\omega t)\]

• \[Q = 1.6 \times 10^{-19} \text{ C}\]

• \[I = \text{constant}\]

Answer 1

Alternating Current varies sinusoidally with time and is represented by \[i = I_m \sin(\omega t)\], where \[I_m\] is the peak current and \[\omega\] is the angular frequency. The expression \[I = \text{constant}\] represents ideal DC.
