The circuit includes three identical light bulbs and a capactior that is fully charged. The power supply provides a steady potential difference. Which light bulb(s) is brightest? I attached the diagrams.

My answer is C. Either that or A and B.
Are my rewritten drawings equivalent to the original?

  • Handwritten label 'original' above a circuit schematic: a battery on the left feeding a loop with resistors labeled A and B across the top, a resistor labeled C in the middle branch, and a capacitor on the right branch.

  • Two circuit diagrams side by side with an 'or' between them. Left: a battery with resistors A and B in parallel, in series with a branch containing resistor C and a capacitor. Right: a battery with resistor A in series with C in one branch, and resistor B in series with a capacitor in a parallel branch.

Consider: What's the voltage drop across Resistor A, B, C and the capacitor in the original. Then compare that to the other 2. Remember wire has a 'negligible' resistance, so across bare wire the potential has to be the same. I'm not answering your homework for you, though.
 
in the original diagram, after current flows through A and through B, it has to go through the horizontal bar in the middle. What happens there, do they cancel?
 
Does current flow through the middle? Current flows from higher potential to lower potential, right? Kind of like a ball at the top of a "potential hill". Label the left junction point 1 and label the right junction point 2 and figure out what the potential is at the points. Then post the current between the to points.
*Edit: The junctions after A and B respectively

Can I pretend the capacitor isn't there since it's fully charged?
And if I do, would A+B be in series with C?

Yes, and yes.
