Concept:At resonance in a series circuit, inductive and capacitive reactances cancel, leaving minimum impedance.
Explanation:In a series resonant circuit, the inductive reactance
XL equals the capacitive reactance
XC.
Their effects cancel, so the total impedance is purely the resistance
R.
Since impedance is at its lowest value, the current flowing in the circuit becomes maximum.
This is because current is inversely proportional to impedance,
I=ZV.
Answer:A. maximum
