Find equivalent inductance at the terminals a and b of the circuit below.
*Round off the final answer to the nearest 4 decimal places with unit. Rounding off should only be done on final answer.
The capacitance of a capacitor is not affected by
A. Distance between plates
B. Area of plates
C. Thickness of plates
D. All of the above
The attached image shows a circuit with an AC voltage source, a resistor, inductor, and capacitor connected in series. The circuit has the following characteristics:
Resistor resistance: 10 ohm
Capacitor capacitance: 0.05 F
Inductor inductance: 13 H
Current Amplitude: 4 A
Voltage amplitude across the source: 60 V
Frequency at the source: 0.3 Hz
Voltage amplitude across the resistor: 35 V
Voltage amplitude across the capacitor: 37 V
Voltage amplitude across the inductor: 80 V
(a) Calculate the RMS voltages from the amplitudes above. From the RMS voltages across the capacitor, inductor and resistor, calculate the RMS voltage of the AC source.
Hint: Vrms = V0/sqrt(2)
Vrms = sqrt( (Vrms,R)2 + (Vrms, L - Vrms, C)2 )
(b) Calculate the RMS value of the current
(c) Using the resistance, capacitance, inductance, and the frequency of the AC voltage, calculate the impedance Z. From this, and the previously measured value of Vrms, find the RMS value of the current in the circuit.
