For ac voltage,voltage of the power supply equals voltage across both capacitor and resistor.
If i connect a CRO across both capacitor and resistor,i in fact measure the voltage of the power supply,right?
According to my lab manual,it states that i can mesure the voltage across the capacitor...
Why the voltage across the capacitor can be measured by connecting a CRO across both the resistor and capacitor ?
actually,i have think of the phase difference and the overall resistance.Still,i can't find the answer.May I get some hints from you?
