@ tim_lou 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) DIAGRAM: _______________ |...|...| R1...R2...R3 |...|...| _ +...|...| - -...|...| |...|...| _______________ (I hope the diagram is...

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...
