How can I find i1? The voltage of the battery is unknown... also, the equivalent resistance will contain one unknown (term R3)... also, i1 would, in itself, be unknown.
There are 3 unknowns and 1 equation... I do not see how your way is possible :confused:
@lightgrav...
QUESTION:
R1 = 2 ohm
R2 = 5 ohm
What value of R3 maximizes the dissipation rate in resistance 3? (battery is ideal -> no internal resistance)

Hello,
I am interested if ANYONE can point a mistake in my reasoning... I am constantly getting a result that is 2X greater than the textbook derivation.
The problem is this:
We have 2 CONDUCTING, infinitely large, oppositely charged plates (far away), each with a charge distribution of...
