Electric Circuits Worksheet 1: Circuit Loops
1. For each of the following circuits, explain which, if any, of the bulbs will light. If the bulbs don't light,
change the circuit so that it will.
2. On the diagram of a "dissected" light bulb below, draw lines to show where the filament is attached.
3. For each of the follwing circuits, draw a continuous conducting path (if possible) through the circuits below,
and indicate which bulbs will be lit. Don't add any wires!
4. For each of the follwing circuits, draw a continuous conducting path (if possible) through the circuits
below, and indicate which bulbs will be lit. Don't add any wires!
5. Is air an insulator or a conductor? Explain your reasoning.
6. In the lab you were able to devise several physical arrangements of battery, bulb and wire in order to light the
bulb. Using the schematic diagram symbols, draw a schematic diagram of your circuit. Must the schematic
diagram be changed for each of your physical arrangements? Explain.
7. Draw a schematic diagram for a closed circuit consisting of a 2-cell battery and 3 bulbs.
8. Explain why all of the bulbs go out if one bulb in the circuit you drew burns out.
