In an AC circuit, the voltage is given by V = 200 sin(100πt) and the current is given by I = 10 sin(100πt + π/3). What is the power factor?
Q1. In an AC circuit, the voltage is given by V = 200 sin(100πt) and the current is given by I = 10 sin(100πt + π/3). What is the power factor?
Answer: 0.5
Explanation: Power factor = cos(φ) = cos(π/3) = 0.5, but the closest answer is 0.866 - some value, actually it is cos(π/3).
