This is a simple RC DC circuit:

Assume initially t=0, Qc=0.
You can adjust DC voltage sourceV_s, Resistor R and Capacitor C and find out how V_R(t)=I(t)*R and V_C(t)=Q(t)/C changed with time.
Since V_s=V_R+V_C=I*R+Q/C, so I=(V_s-V_c)/R=\frac{V_s-Q/C}{R} this is the only equation used in EJS to create the simulation.
So it is very easy to create simulation with EJS. Enjoy it!

  • 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!
