The output of an ac generator has a maximum value of 240 V. At what angle is the instantaneous voltage equal to 85 V?
A) 69.3°
B) 19.5°
C) 90°
D) 20.7°

Question

Quizplus · Accepted Answer

The instantaneous voltage (V) of an AC generator can be found using the formula V = Vmax * sin(θ), where Vmax is the maximum voltage and θ is the angle in degrees. Given Vmax = 240 V and V = 85 V, we solve for θ: 85 = 240 * sin(θ). Solving for θ gives θ ≈ 20.7°.
