Hi there, I am very confused now, please help me with this circuit problems: For the circuit shown in the diagram, a. Find the readings on teh ammeters A, B and C( assumed to have effectively 0 resistances) b. Find the p.d. between X and Y. c. Find the power dissipated as heat in the circuit. d. Find the power delieverd by the 12 V cell. e. Account for the differences between c. and d. Sorry, I am not asking you to do the homework for me, but I really don't know how to start off when so many cells are connected together.
