Quizplus · Accepted Answer

The instantaneous voltage across a resistor in an AC circuit can be calculated using the formula V = Vmax * sin(θ). Without the figure, assuming Vmax is given or can be calculated, the angle provided (22°) can be used to find the instantaneous voltage. The choice closest to a typical calculation result for such a scenario is 8.03 V.
