1. Decide which of the following statements are true about an electric circuit. List all that apply.

a) Electrons are the mobile charge carriers in an electric circuit.

b) The path of charge flow from the + to the - terminal of the circuit can consist of nonconductive material.

c) In an electric circuit of an automobile, the 12-Volt car battery is sometimes referred to as the internal circuit because it is located inside of the hood of the car.

d) Charge is supplied with energy in the internal circuit and the energy is transformed into other forms in the external circuit.

e) Charge is consumed as it moves through the energy-transforming devices of the external circuit. For instance, the amount of charge entering a light bulb in a second is less than that which exits the light bulb in a second.

f) A battery is used to power a flashlight circuit. When the battery no longer works, it is because it has run out of charge.

g) The location on an electric circuit where the charge possesses the greatest amount of electric potential energy is the + terminal of the battery.

2. Decide whether the following statements are true or false:

1. When a battery no longer works, it is out of charge and must be re-charged before it can be used again. 2. A battery can be a source of charge in a circuit. The charge that flows through the circuit originates in the battery. 3. Charge becomes used up as it flows through a circuit. The amount of charge that exits a light bulb is less than the amount that enters the light bulb. 4. Charge flows through circuits at very high speeds. This explains why the light bulb turns on immediately after the wall switch is flipped. 5. Electrons are negatively charged 6. Total resistance in a series circuit is the sum of the individual resistors

True / False True / False True / False True / False True / False True / False

3. Rearrange the letters to find the electric connection and match it to the pictures below.

A ____________ is used to turn a circuit on or off. 9. The circuit that takes electricity in and around your home is called the ____________. 10. A ____________ breaks a circuit if too much electricity tries to go through.

11. A circuit in which all charge follows a single pathway is a ____ circuit; a circuit in which charge follows multiple pathways is a ____ circuit.

a. series, parallel b. parallel, series

12. For a parallel circuit: as the number of resistors being used within the same parallel circuit increases, the overall resistance value _____________________________ (increases, decreases) and the overall current value _____________________________ (increases, decreases).

13. Household circuits are connected in parallel so that _____. Select all that apply.

a. houses get the same effect with less current and thus save on energy costs

b. the turning off of one appliance does not result in the shutdown of others

c. the hazard of electrocution and overheating of circuits is avoided
