How can the Power-Angle equation be used to calculate power in a circuit?

• P = I^2cos(θ)

• P = VIsin(θ)

• P = VIcos(θ)

• P = V^2cos(θ)

Solve the following Power-Angle equation problem: P = V * I * cos(θ), where V = 10V, I = 5A, and θ = 30 degrees.

• P = 10V * 5A * cos(30°) = 10V * 5A * 1 = 50W

• P = 10V * 5A * cos(30°) = 10V * 5A * 0.5 = 25W

• P = 10V * 5A * cos(30°) = 10V * 5A * 0.707 = 35.35W

• P = 10V * 5A * cos(30°) = 10V * 5A * 0.866 = 43.3W

Create a graph to represent the Power-Angle equation with the following values: P = 100W, V = 20V, and I = 5A.
