Challenge Problems
Push your limits with advanced challenges
Given a circuit with voltage V = 220∠0° V and impedance Z = 100 + 50j Ω, calculate the current and its phase angle.
💡 Hint: Use I = V/Z after converting Z to polar form.
Convert the complex impedance Z = 6 - 8j to polar form and then calculate its current if the voltage is 120∠0°.
💡 Hint: Do the calculations stepwise; first convert, then use Ohm's Law.
