What happens when inductive and capacitive reactance are equal in a series LC circuit?
Resonance causes impedance to be very high
Impedance is equal to the geometric mean of the inductance and capacitance
Resonance causes impedance to be very low✓Правильный ответ
Impedance is equal to the arithmetic mean of the inductance and capacitance
Объяснение
Inductive and capacitive reactance are opposite in sign, so when they are equal in magnitude they cancel and only the small series resistance remains, making impedance a minimum and current a maximum. Very high impedance at resonance describes a parallel LC circuit, not a series one.
