Three identical light bulbs are connected with wires to an ideal battery. The two terminals on each socket connect to the two terminals of its light bulb. Wires do not connect with one another where they appear to cross in the picture. Ignore the change of the resistances of the filaments due to temperature changes.
(a) Which of the schematic circuit diagrams correctly represent(s) the circuit? (List more than one choice if more than one diagram is correct.)
(b) Which bulb(s) is/are the brightest? Which is/are the dimmest? Or are they all the same? Explain.
(c) Find the current through each bulb if the filament resistances are each 24.0 Ω and the emf is 6.0 V.
