A series circuit has R = 60 ohm, inductive reactance 100 ohm and capacitive reactance 20 ohm. What is the impedance?
Answer and explanation
Correct answer: A. 100 ohm
- Step 1: Z = sqrt(R squared + (XL - XC) squared).
- Step 2: Z = sqrt(3600 + 6400) = 100 ohm.
Answer
100 ohm.
Why not the others: 180 ohm, 140 ohm and 10000 ohm do not fit.
