Hi friends,
I have an interesting question from a professor ~
We have two capacitors with the same capacitance (note: C1 is charged up by half and C2 is empty). Let's say, they are now charged up separately by the same source, i.e.
V1---R1---C1 & V2---R2---C2 where V1=V2, R1=R2, C1 is charged up by half initially before connecting to the source and C2 is empty before connecting to the source
Questions:
(1) Which capacitor has a higher initial dV/dt?
(2) Which capacitor will be charged up first?
Professor's answer:
(1) C2
(2) C1 <--- I doubt this answer. Maybe the professor was making joke
Any comments are very welcome !!
