Question 1
What is the formula for impedance in an LCR circuit?
- Z = R + X
- Z = β(RΒ² + (X_L - X_C)Β²)
- Z = R - X
π‘ Hint: Think about how we represent inductive and capacitive effects in circuits.
Question 2
In a purely capacitive circuit, does current lead or lag voltage?
- True
- False
π‘ Hint: Recall the phase relationships we've discussed.
