Problem 3 Version B: An RLC circuit is connected to an AC source (50 Points) as shown in the diagram. The supply voltage is given by (155V) sin(100rt), where t is in seconds. Find: 1. The overall circuit impedance for 25 < 0 < 360 mH. 2. The RMS voltage across each circuit element. 3. The AC average power loss in the source. 4. The resonance frequency. 5. The circuit impedance and power loss at the resonance frequency.
