Draw a graph between voltage and currenrt in case of an AC circuit containing only inductor.

Text Solution

AI Generated Solution

To draw a graph between voltage and current in an AC circuit containing only an inductor, we can follow these steps: ### Step 1: Understand the Relationship Between Voltage and Current In an AC circuit with an inductor, the voltage (V) across the inductor leads the current (I) by a phase angle of π/2 (90 degrees). This means that when the voltage is at its maximum, the current is at zero, and vice versa. ### Step 2: Write the Expressions for Voltage and Current Assuming the voltage is given by: \[ V(t) = V_0 \sin(\omega t) \] ...
