HI there,
I have a 100n Capacitor in series with a 1K resistor connected to a function sine generator at 1KHz. I used 2 channels of my scope to see the voltages and waveforms acroos the cap and the resistor. I know how to calculate the current going through the circuit by ohm's law but I am not sure how to do it by this formula:
Ic= c dV/dt
Since the input voltage (coming from function generator) is sinusoidal then the voltage across the cap is cosine. I am able to see the waveforms and their value by my digital scope but not sure how to calculate Ic (actually I do not know what to do with dV/dt). I think dV/dt will be equal to coswt but I can not go ahead....
Please help
Thanks
