Case Studies
If a circuit has two bulbs, then they are identical. But the bulbs in one circuit are not identical to the bulbs in other circuits. 
Law Breakers
The diagrams represent bulb brightness using starbursts and current using arrowtails. Give attention to the relative brightness of bulbs, to the relative current in wires, and to the current direction. Select any diagrams that incorrectly convey a current concept.
