Question

A. An input signal of 10V at 0degree is applied to a parallel RLC circuit with resistor R=100 ohm, inductive reactance XL=200ohm, and capacitive reactance XC=200ohm. All three components are connected in parallel to the source. The source current is?

B. An input signal of 10V at 0degrees is applied to a parallel RLC circuit with resistor R=100ohm, inductive reactance XL=100ohm, and capacitive reactance XC=50 ohm. All three components are connected in parallel to the source. The complex admittance in siemens as seen by the source is?

Explanation / Answer

X=XL-XC =200-200

X=0

so Z=R =100 ohms

Is =V/Z =10/100

Is=0.1A

b)

Y =1/100 +1/00 +1/50

Y=0.04 siemens
