Created by StemPy LabIn a series LCR circuit, voltmeters show V across the resistor, V across the coil and V across the capacitor. All are rms readings. What is the power factor of the circuit?

← A series LCR circuit takes 380 W from a source of fixed voltage when it is in resonance. The frequency is then changed to a value at which the net reactance has the same size as the resistance. How much power does the circuit take now?An alternating emf is e = 18 sin(100π t), with e in volt and t in second. What is its time period? →
