Dear people of Electro Tech,
I study Engineering in Belgium, and I'm studying for my Electronic exam for in a few weeks.
While I was reading about the integrator setup using opamps, I found something that I have trouble to understand.
This is the setup:
**broken link removed**
I know when you have a capacitor in serie with a resistor, you have the differential equation : V = q/C + R*dq/dt, when solved yields Vc = V*(1-e^-t/RC).
However, the capacitor charges up lineair when a constant Voltage is applied at Vi in the setup above. Does it not stand in series with the resistor, as there should flow no current into the opamp?
Thank for reading,
