Physics · Alternating Current
In a series LCR circuit, what happens to the total impedance and current when the circuit reaches its resonant frequency?
- 1The current becomes zero because the reactances cancel each other out
- 2The impedance equals the sum of inductive and capacitive reactances
- 3The impedance is minimum and the current is maximum✓
- 4The impedance is maximum and the current is minimum
Correct answer
The impedance is minimum and the current is maximum
