Exploring Electricity Concepts

What is electric current?

• Electric current is the flow of electric charge.

• Electric current is the speed of light.

• Electric current is the resistance of a circuit.

• Electric current is a type of voltage.

What unit is electric current measured in?

• watts

• volts

• ohms

• amperes

Name a common conductor of electricity.

• Plastic

• Copper

• Wood

• Rubber

What is an insulator?

• A conductor that enhances the flow of electricity.

• A device that generates electricity efficiently.

• A material that amplifies heat transfer.

• An insulator is a material that resists the flow of electricity or heat.

Give an example of an insulator.

• Copper

• Aluminum

• Iron

• Rubber

What does Ohm's Law state?

• R = V - I

• I = V + R

• V = I * R

• V = R / I

What is the formula for Ohm's Law?

• V = R / I

• I = V + R

• R = V - I

• V = I * R

What is the unit of resistance?

• Ohm

• Joule

• Watt

• Volt

What happens to current when resistance increases?

• Current increases when resistance increases.

• Current remains constant when resistance increases.

• Current decreases when resistance increases.

• Current fluctuates randomly with resistance changes.

Define static electricity.

• Static electricity is the buildup of electric charge on the surface of objects.

• Static electricity is the energy produced by moving electrons in a circuit.

• Static electricity is the phenomenon of electric charge moving through the air.

• Static electricity is the flow of electric current through a conductor.
