• clockwise

• towards the switch

In this picture, Bulb #1 is very BRIGHT, Bulb #2 is very DIM, and bulb #3 never turns on. Which Material is the best insulator?

• Material #1

• Material #2

• Material #3

• All the materials insulate the same

In this circuit, what would happen if the wire between the top and middle lightbulb were cut?

• The bottom light bulb would stay on

• The top light bulb would stay on, but the other 2 would go out

• The bottom 2 light bulbs would get dimmer

• All 3 light bulbs would turn off

This is the "push" that makes electrons flow through a circuit

• Voltage

• Current

• Resistance

• Load

This is the opposition to the flow of electrons

• Voltage

• Current

• Resistance

• Energy Source

When Voltage increases, what else increases?

• Resistance

• Current

• Insulation

• Conduction

When resistance increases, what else happens?

• There is more conduction

• Electricity flows faster through your circuit

• Voltage and Current also increase

• Voltage and Current decrease

What is one ADVANTAGE to parallel circuits?

• If a wire is cut, it's possible for electricity to continue flowing

• It increases resistance in your circuit

• It supplies less voltage to the each part of your circuit

• It increases current
