How High Pass Filters Work using a Resistor and Capacitor (RC)

I explain how high-pass RC filters work using the falstad circuit simulator and a circuit which is similar to the one used with the low pass filters in a previous video. The simulations include the circuit diagram showing current flow, capacitor operation, time-domain voltage plots at various frequencies, and a frequency response plot. Below is the text of the code I used in Falstad: $ 1 0.000005 14.235633750745258 55 5 50 5e-11 v 176 256 176 80 0 2 85 5 0 0 0.5 r 176 80 336 80 0 187 c 336 80 336 256 0 0.000009999999999999999 -4.2244607677073445 0.001 w 176 256 336 256 0 o 0 16 0 x81016 20 0.2 0 14 2.5 0 1 3 0.05 0 2 3 0.05 0 1 3 0.05 0 2 3 0.05 0 2 3 0.05 0 1 3 0.05 0 2 3 0.05 0 1 3 0.05 0 2 3 0.05 0 1 0 2.5 0 1 3 0.05 0 2 0 2.5 0 2 3 0.05 0 38 2 F1 0 0.000001 0.000101 -1 Capacitance
