Calculate Instantaneous Current





Formula

The formula to calculate the instantaneous current (I(t)) is:

\[ I(t) = I_m \times \sin(w \times t) \]

What is Instantaneous Current?

Instantaneous current is the current flowing through a circuit at a specific moment in time. In an AC circuit, this value varies with time, following a sinusoidal pattern. The calculation of instantaneous current is important in understanding the behavior of AC circuits and the power consumed by electrical components over time.

Example Calculation

Consider an example where:

Using the formula to calculate the instantaneous current:

\[ I(t) = 5 \times \sin(2\pi \times 0.1) \approx 5 \times \sin(0.2\pi) \approx 5 \times 0.5878 = 2.939 amps \]

This means that the instantaneous current at this time is approximately 2.939 amps.
