Homework Statement

Could you please help me to start this question?

Calculate the properties of complex periodic waves.

A 100Ω resistor is connected in series with a 2 uF capacitor and a 20 mH inductor. The voltage
1 sin 5000t+0.5 sin 1000t V is applied across the circuit.

Determine:
1. the effective ( rms) voltage
2. the effective (rms) current
3. the true power
4. the power factor

Thank you!

How do you think you should approach this problem? Have you been studying phasors in this class? Or are you supposed to use differential equations to do the calculations?

If you have been studing phasors, what are the impedances of each of the 3 components?

What is the equation that defines the power factor of a circuit?

I have been studying away from college cause I am working. Its hard subject, specially if english is not your first language.
Its always difficult to start the question, cause you need to know what they are asking you to do.

The simple equation for power factor: PF= R/ Z
