RC circuits -- questions about the solution
First of all , greetings from Peru and thank you to all the people who help another people here,taht's awesome , please help me with this guys... Here's the statement
The solution is
My questions:
ok my question is about the solution for the question "c", it says that the current is the sum of the current produced by the battery and the current produced by the dischargin process,well ,my teacher told me that after that a capacitor is fully charged by a battery , the current is zero because there is no pottential difference between them. so, :
1. Why the solution adds the current produced by the battery? why isn't it zero?Isn't it zero at t=0 too?
2.why they say the current at the closed switch is the sum of both currents whithout drawing directions of both currents?( you know like kirchhoffs junction rule,i've checked out some solutions of this problem and they don't draw the directions they just say it's the sum of both currents)
