Electric Circuits

We used solar panels or lemons as a source of electricity and a device and connected them all with wires. What did we create?

• A resistor

• A circuit

• A circus

• A circuit breaker

A complete closed circuit through with electric charges can flow is a(n)

For current to flow, a circuit must be

• closed.

• open.

• outside.

• insulated.

Electricity is dangerous only when labeled as "high voltage"?

• We only have to worry about household uses of electricity.

• There are no safety measures we can take regarding electricity.

• Electricity is a safe and reliable source of power. No precautions needed.

• Electricity is dangerous, no matter the voltage, if not used correctly.

An electric circuit is composed of 3 basic parts and they are:

• An energy source, an electrical current, and a load.

• An energy source, an electrical conductor, and a resistor.

• An energy source, an electrical conductor, and a load.

• A battery, an electrical conductor, and a toad.

Chemical or nuclear energy is turned into electrical energy:

• in a battery

• by a wall socket

• by a hydroelectric dam

• at a power plant

Good electrical conductors allow electricity to flow freely and include:

• pure water

• copper

• plastic

• wood

A solar cell creates electrical energy from

• kinetic energy

• light energy

• potential energy

• mechanical energy

The function of electrical insulators is

• To keep people from getting harmful shocks from the conductor of the electricity

• To keep the wires warm

• to keep the electric bill low

• Act as resistors

A device that uses electrical energy to operate is called a
