The figure shows an RLC circuit.
What is the total impedance of the circuit?
What is the phase angle between the current and the emf in the circuit?
An RLC series circuit consists of a 50- resistor, a 200-F capacitor, and a 120-mH inductor whose coil has a resistance of 20 Ω. The source for the circuit has an rms emf of 240 V at a frequency of 60 Hz.
Calculate the rms voltage across the resistor.
Calculate the rms voltage across the capacitor.
Calculate the rms voltage across the inductor.
An alternating current generator is connected to a device whose internal circuits are not known. We only know current and voltage outside the device, as shown in the diagram. What is the power dissipated by the circuit?
