A unknown circuit element X is connected in series with a resistor R to an ac source. If VAB = VAC (rms value), then X is-
A
Pure resistor
B
Pure capacitor
C
Pure conductor
D
Combination of conductor & capacitor at resonance
Answer
Combination of conductor & capacitor at resonance
Explanation
Solution
At resonance
VBC = 0
\ VAB become equal to VAC.
