Question 1
What is the formula to calculate total impedance in a series RLC circuit?
- Z_total = R + j(X_C - X_L)
- Z_total = R + j(X_L - X_C)
- Z_total = R - j(X_C + X_L)
💡 Hint: Focus on the contributions of L and C to the total impedance.
Question 2
True or False: In a series circuit, the voltage across each component can be different.
- True
- False
💡 Hint: Think about how voltage divides in a series circuit.
