Electric Circuits

1. Which of the following statements best compares the functions of parts A & C?

• Part A generates the energy needed for electricity, while part C conducts the flow of electricity.

• Part A absorbs the flow of electricity, while part C generates the energy needed for electricity.

• Part A opens and closes the flow of electricity, while part C transfers the flows of electricity.

• Part A is the device activated by the electricity, while part C controls where the electricity goes.

2. Which of the following statements best describes parts B & D?

• Part B is the conductor, or wire, and Part D is the battery, or load

• Part B is the circuit or conductor, and Part D is the load, or switch

• Part B is the battery, or power source, and Part D is the bulb, or load

When you have a circuit that has the different parts of the circuit on separate paths or branches, it is called a ____

• series

• open

• parallel

• closed

What happens to the energy from the d-cell when connected to a circuit with a light bulb?

• It stays in the battery.

• It is transferred to the bulb and changed to light energy.

• It flows through the wire and produce heat energy.

• It travels through the wire and stops at the bulb.

3. One disadvantage of this type of circuit is that

• The addition of new lights decreases resistance

• As more lights are added to the circuit, the voltage of each decreases

• As more lights are added, the voltage of each increases

• When the circuit to one light is turned on, the circuit to the other lights turns off

A ________ is used to open and close a circuit.

• wire

• load

• d-cell

• switch

A continuous flow of electrons is called a ______.

• resistance

• current

• load

• voltage

9. In which of the following connections will light turn on?

• 1, 2 and 4 only

• 4 and 5 only

• 5 and 6 only

• 1, 3 and 5 only

10. Which of the following is NOT TRUE about the energy in the d-cell?

• It is stored in the form of chemical energy.

• It has no energy unless connected in a circuit.

• It can change form when used in a circuit.

• It travels from the d-cell through the wire to the load then back to the cell.
