1.	A series RLC circuit has a resonant frequency of 550 Hz. The maximum voltage across C is likely to occur at a frequency of ___________(a) 1000 Hz(b) 2000 Hz(c) 1025 Hz(d) 500 HzI had been asked this question at a job interview.My question is from Advanced Problems on Network Theory topic in portion Network Theory and Complex Circuit Diagram of Network Theory
Answer» Correct option is (d) 500 Hz For explanation I would say: We know that, maximum voltage across CAPACITANCE occurs at a frequency slightly less than RESONANT frequency. Here, given that resonant frequency = 550 Hz. So, out of the given options 500 is the LOWEST nearest integer to 550. Hence, 975 Hz.
