In an L-C-R series resonant circuit, the capacitance is changed from C to 4C. For the same resonant frequency, the inductance should be changed from L to
Options
(a) 2L
(b) L/2
(c) 4L
(d) L/4
Correct Answer:
L/4
Explanation:
We know that, In L-C-R circuit, f = (1 / 2π) √(1 / LC) For the same resonant frequency, the inductance should be changed from L to (L / 4).
