Try it on paper first. A hint, the key idea and the worked solution are here when you need them.
A circuit has and a net reactance of . It is joined to a V (rms) source. Find the impedance, the rms current, the power factor, the average power and the apparent power.
The average power is . The power factor is . The apparent power is in VA.
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. The impedance. .
Step 2. The current. A.
Step 3. The power factor. .
Step 4. The powers. The average power is W. The apparent power is VA.
Answer: , A, , W and VA.
Check. W. It fits.
