This applet is Rc circuit (DC: charge/discharge)

Original project RC circuit (DC: charge/discharge)

For the charging cycle:V_s=V_R+V_C=I R + \int \frac{I dt}{C} where Vs is the voltage from the power supply.
0=R \frac{dI}{dt}+ \frac{I}{C}, \frac{dI}{dt}=-\frac{I}{RC}, so the solution is I(t)=I_0 e^{-t/(RC)}
at t=0, V_c=0 so I(t=0)=I_0=V_s/R
The result is V_R(t)=I(t) R =V_s e^{-t/(RC)}, V_c(t)=V_s-V_R(t)= V_s (1- e^{-t/(RC)})

  • 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!
