Questions

 * 1) A parallel circuit is a circuit that has multiple ways travel.
 * 2) The Earth acts as an insulator.
 * 3) As the resistance increase, the current increases.
 * 4) A short circuit is when there is __. A: No resistance B:No voltage C: No load D: No current
 * 5) What is not an insulator. A: Wood B: Glass C: Rubber D: None of the Above
 * 6) In the balloon simulation, what happened when the negatively-charged balloon was moved near the wall?
 * 7) What happens when more loads are added to a circuit? (And what //are// loads, anyway?)
 * 8) How strong of a current (don’t forget your unit of measurement) will a typical circuit breaker tolerate?
 * 9) Explain how a flashlight works and draw a schematic of a flashlight.
 * 10) Draw the symbols for a motor, a buzzer, a light bulb, a switch, a speaker, a battery, a wire, and an LED.
 * 11) Explain how a lightning rod works (and why it is useful).
 * 12) Draw a diagram of how electrons travel through a light bulb.

Answers

 * 1) (True)
 * 2) (False)
 * 3) (False)
 * C
 * D
 * 1) The negative charges/electrons in the wall were repelled from the negatively-charged balloon. The balloon was then attracted to the positive charges in the wall and "stuck" to the wall.
 * 2) When more loads are added to a circuit, the resistance goes up because it is the loads' esistance that makes the electrons power them. A load is any appliance, such as a light bulb, a buzzer, or a speaker, that requires electricity to power it.
 * 3) A typical household circuit breaker will tolerate about 15-20 amps. If the current becomes stronger than that, it will break the circuit.
