Ejs Open Source RLC AC Model java applet

The code has been modified so that you can remove one or two elements.
Now you can study pure resistor circuit, RC, RL, LC or RLC circuit with this simulation.
I also add small circle along the circuit loop to simulate the average motion of charge particle in the loop.
The current flow I in the loop in proportional to (in phase) the voltage of the resistor VR.
However, there is a 90 degree out of phase between voltage of inductor/capacitor and the current I.
The slider bar on the left is used to adjust the voltage of the source. V

• Please feel free to post your ideas about how to use the simulation for better teaching and learning.
• Post questions to be asked to help students to think, to explore.
• Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!

color codes the sliders
added text and symbols $//omega$, original did not work in my PC
shift text "V" to the side for greater clarity away from the circle of AC source
made world view bigger for ease of projecting in classroom use
add symbolic play step and reset buttons, didn't see how the initialize does so remove it

can not do
the text cannot be subscripted by using "_", is a Ejs 4.3.1 version problem or do i need to reprogram the logic for subscripts to appear?

Enjoy!
