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
Correct Answer: A. 112.5Hz
Explanation
fo = \(\frac{1}{2 \pi \sqrt{LC}} = \frac{1}{2 \times 3.14 \sqrt{1 \times 2 \times 10^{-6}}}\)
= 112.5Hz
