The wave form of a sinusoidal current passing through a circuit?

Click For Summary
SUMMARY

The discussion focuses on deriving expressions for the voltage across a capacitor (V_C) and an inductor (V_L) in a circuit with a sinusoidal current I = I0sinωt. Participants emphasize the importance of understanding the phase relationship between the current and voltages, particularly at the resonant frequency where the magnitudes of V_C and V_L are equal. The equation Lω0 = 1/Cω0 is highlighted as crucial for relating the resonant frequency to the circuit components. Additionally, the need to sketch waveforms for I, V_C, and V_L over 1.5 periods is discussed to visualize these relationships.

Assume a sinusoidal current I = I0sinωt passes through the circuit of:

[PLAIN]http://a.yfrog.com/img52/9062/image2c1.jpg

Obtain expressions for VC and VL in terms of ω and I0. Sketch the waveform for I, VC and VL, to show the phase relationship between these three variables. (Show about 1.5 periods; relative size of the amplitudes are not important here.)

Also use the fact that the magnitude of the voltages VC and VL are equal at the resonant frequency in order to obtain the expression involving ω0 shown as in the Equation: Lw0=1/Cw0


Ok, I've read the question but don't know exactly what its asking me to do, I know I need to draw a wave function but other than that I'm stumped. Can someone explain this question to me in dumbed down terms so I can have a crack at it? Thanks for any help guys.

Seems like the problem wants you to find equations for the voltage across the capacitor (V_C), and inductor (V_L) in terms of the frequency and voltage.

Do you know what phasors are?
