Hello

Is that true, if capacitor connect across constant DC voltage source, output voltage of capacitor does not change, also the current through capacitor does not change. If yes than how to proof mathematically

Let's take example, 4F capacitor which has internal resistance is 2 ohm connected across 10 volt DC supply

1. Find out voltage across capacitor

2. Find out current through capacitor

According to definition, voltage across capacitor will be 10 DC.

We know formula i=c(dv/dt)

I=4*?

Another formula v=i*r

We know voltage drop across capacitor v=10v DC, internal resistance r=2 ohms

Thus i=10/2=5 amps

How to proof mathematically, if capacitor connected across DC voltage source neither voltage across capacitor nor current through capacitor change ,

please guide me on right direction.
