I have just done an experiment on CR and LR circuits.
http://img9.picsplace.to/img9/21/RC.jpg
Connect channel 1 of the CRO across both the capacitor and resistor and channel 2 across the resistor.The trace on channel 1 is taken as the p.d. across the capacitor and that on channel 2 as ths current throught the capacitor.

Replace the capacitor waith a high inductance coil fitted on a double C-core.
I have some questions about this.
Why is channel 1 is connected across both the capacitor and resistor and not only the capacitor?
Why the trace on channel 2 gives the current throught the capacitor?
When we increased the resistance value, the phase difference decreased.Why?
I have so many question to ask ..
