1. The problem statement, all variables and given/known data We are examining an RC circuit with a scope. A square wave is applied to the circuit. Sketch the square wave and the trace giving the voltage across the capacitor. Explain your results. 3. The attempt at a solution So I got something like this. Now the way understand it is that during the first half-cycle, the capacitor is being charged, so the electric potential across the capacitor increases to some value, then when the square wave switches, is it discharging or charging to a negative value? Just a little clarification there would be greatly appreciated!
