An inductor of inductance 1.0H is connected in series with a capacitor of capacitance 2.0\(\mu F\) in an a.c. circuit. to resonate
A
112.5Hz
B
225.0Hz
C
323.5Hz
D
707.1Hz
Verified Correct Answer: A.
Physical Principles & Numerical Solution
fo = \(\frac{1}{2 \pi \sqrt{LC}} = \frac{1}{2 \times 3.14 \sqrt{1 \times 2 \times 10^{-6}}}\)
= 112.5Hz
