Challenge Problems

Push your limits with challenges.

Question 1

An AC circuit contains a pure resistor, an inductor, and a capacitor. The RMS voltage is 120V, the resistance is 40 ohms, and the inductor has an inductance of 0.1H while the capacitor has a capacitance of 100ΞΌF. Calculate the RMS current through the circuit.

πŸ’‘ Hint: Find the frequency to calculate the reactances.

Question 2

In a series AC circuit, if the phase angle is known to be 45 degrees, find the real power consumed if the system operates at an RMS voltage of 240V and RMS current of 10A.

πŸ’‘ Hint: Use the cosine of the phase angle for power calculation.
