    The circuit is 1. (10 V (cell) and 5 ohm. (resistance) in series) 2. (5 V and 10 ohm. in series) 3. ( 20 V and 5 ohm. in series) 4 (30 V and 11 ohm. in series) 1, 2, 3, and 4 are all connected in parallel to each other and also to a 25 V cell.

    Thank you for replying Mr. Jacobs, But how did you get the resistor's in parallel? The resistors have all their ends connected to each other only on one side and the others sides are connected to the batteries. For the resistors to be in parallel, shouldn't the sides on the batteries also be connected to each other? The same holds for the batteries. The potential is the same for resistors in parallel, but these resistors are connected to different emfs, so won't the potential be different. So, this implies that they are not in parallel. Please explain this part.
