We have a circuit with a battery, two resistors, a switch and a capacitor. We assume that the battery has a switch so that we can choose whether it should be a voltage source for the circuit.
a) At time t = 0, we put on a voltage Vs
over the battery in the circuit. What is the current over the resistors and over the capacitor?
b) At time t = 0, we put on a voltage Vs
in the circuit. What is the charge on the capacitor as a function of time? What is the current over R2
as a function of time?
The Attempt at a Solution
I assume that the circle with the V inside is the switch. I guess I have to use
Kirchhoffs first and second law somehow, can someone give me hints? I not sure if understand the different components of the diagram, where is the switch for instance?
