I have three questions
1. How do you find AC voltage across resistor when there are both AC and DC current?
2. is AC voltage across a resistor different from voltage across a resistor?
3. Find AC voltage across Resistor (in this image)
load line Eq: V(ec)=12-6000*I(c)
Voltage across resistor = I*R
but I do not know if this can be used when there are mixture of
The Attempt at a Solution
well I tried making a AC current by removing battery out of the circuit. I would still get around 3 volts. Also tried using V(max) and V(min) and calculated for I*R(l), but got around 6 volts (which is way off)
now I'm out of ideas. (well I do not understand the problem fully in the first place)
Do I need to use the chart on the bottom?
by the way, does this topic (or anything under circuits, electric fields, and optics-related physics) belong to advanced physics? or is this in the right section?)
