What is the formula for calculating total impedance in a series AC circuit?
Correct Answer: Z = R + jX
- Step 1: Understand that in a series AC circuit, there are two main components: resistance (R) and reactance (X).
- Step 2: Recognize that resistance (R) is the opposition to current flow in a circuit.
- Step 3: Know that reactance (X) is the opposition to current flow caused by capacitors and inductors in the circuit.
- Step 4: Realize that total impedance (Z) combines both resistance and reactance.
- Step 5: Use the formula Z = R + jX to calculate total impedance, where 'j' represents the imaginary unit.
