# Homework Help: Electrical engineering, RLC circuit

Alright, here I come again for help!

In a series R, L, C circuit, the values of the passive elements are R=5ohm, L=1H, and C=10uF. The output voltage is taken across R, and te input voltage signal is of variable frequency. Using Electronics Workbench, obtain a plot of V0(t) as a frequency f over a sufficiently large frequency band which is roughly bisected by the resonance frequency.

Okay, all I dont get is "obtain a plot of V0(t) as a frequency f over a sufficiently large frequency band which is roughly bisected by the resonance frequency."
What is meant by "a sufficiently large frequency band which is roughly bisected by the resonance frequency."?

THANK YOU! THIS IS A TAke hoME QUIZ!

Hint -- the only things resonating in the circuit are the L & C, since the resistor cannot store energy. So what is the resonant frequency of an LC circuit? And for sufficiently large frequency band, start with a couple of decades above and below the resonant frequency, and pare it down if nothing interesting is happening outside +/1 one decade. Let us know what you find...
