This java applet will show you physics properties of an R-L-C circuit.
driven by a harmonic voltage source¡C

You will find a popup window when you click.
(wait unitl start appear)

A new window will popup when you click the start button)

1. The peak value of AC source is fixed at 10.0 V
and the resistor is 1.0 k?.

2. Parameters you can change:
1. The period of the AC source (enter into the textField)

The unit can be in  s , ms (10-3s), us(10-6s), ns(10-9s)

2. You can change the inductance L
Click the mouse within the inductance region (blue coils)
Click left button to decrease its value.
Click right button to increase its value.
The increasement is determined by delta* choicebox
3. You can change the capacitance with the same method.
4. Press Start for animation

 Red Curve Yellow Curve blue curve green curve V VR VL VC

5. White small circle simulate the AC current,
its velocity is propotional to current I.
6. If the mouse button is within the curve (time-voltage)region,
The coordinate of the mouse will be translated and displayed.
Click near (time, voltage)=(0.s, 10.0v) and
drag the mouse up and down to change y scaling factor.
7. Press mouse button to suspend the animation.
If you click the left mouse button,
animation resume when you release the mouse button.
If you click the right mouse button,
you need to click it again.
8. Press Reset button to reset parameters.
9. Press Quit or Close the window to Quit.

Observation:
1. Phase between VC(Voltage of capacitor) and VL(Inductor)
2. phase between VR(Resistor) and VL or VC.
3. Relation between VL and oscillator frequency f= 1/T(period).
How to increase VL ?
4. Relation between VC and oscillator frequency
How to increase VC ?
5. VR is propotional to I (current).
How to increase the current?
What is the relation between VL and Vc when I is maximum ?
6. V = VR + VL + VC
In the above picture, VL(blue) > V(red) Why

hi,

I was just going through the java applet that you have created for the RLC circuit with as AC source. just wokering if I could have the source code for the applet, I would like to modify it to my need for calculation purposes, if thats ok with you?

Thanks and Regards,

Hassan M Malik

The above simulation with work sheet allow you to play and find phenomena related to RLC AC circuit.

You are welcomed to write down your observation and we can discuss.
There is no standard solution, because it is not a problem, but activity for learning.
