when we're measuring the voltage of generator and the voltage across the resistor, why dont the waves line up?
Thanks

Just think about what a resistor does to the current and therefore the voltage
ReplyDeleteAlso, think about what other elements were in the circuit. Would there be any difference between the phase of just an R circuit (one with only a voltage source and a resistor) and an RC circuit? an LRC circuit?
ReplyDeleteIt's an RC circuit. I'm not fully understand how the current through and voltage accross the resistor affected when the capacitor is charging.
ReplyDeleteA capacitor is charging, means there's a flow of charge into the capacitor, so current is increasing hence the voltage. But then what happen to the resistor?
Everything is decreasing?
The two waves on the scope belong to Vac and VR, so which voltage is ahead?
I think I wrote that down on my lab but don't have it with me
