MHT CET 2024 Physics question
An inductor of inductance H is connected in series with a resistance a variable capacitor and an a.c. source of frequency 5 KHz. The value of capacitance for which maximum current is drawn in to the circuit is F where the value of 'x' is
Answer: (C)
Solution
Maximum current is drawn at resonance, when , i.e. . Here rad/s, so (using ). Then \frac{1}{ω^2L}\frac{1}{10^9×2×10^{-6}}$ =
