What is the function of a switch in an electrical circuit?
It opens and closes the circuit.
What is the function of a load in an electrical circuit?
It converts the electricity into another form of energy. ( A bulb converts electrical energy into light energy)
TRUE or FALSE: Open circuits have electrical current.
FALSE: Electrical currents can't flow in an open circuit.
TRUE or FALSE: Neutrons attract electrons.
FALSE: Protons attract electrons because they have opposite charges
TRUE or FALSE: If you see lightning at the beach, go swimming to stay safe.. (Explain your answer using the words insulator OR conductor))
FALSE: Sea water is an electrical conductor. If the lightning strikes the water, you can get a shock.
Why are electrical wires made of copper covered in plastic? (Use the words electrical conductor /insulator)
The wire conducts electricity because copper is a conductor but the plastic on the outside of the wire protects us because it's an insulator.
TRUE OR FALSE: The nucleus of an atom contains protons and neutrons.
TRUE: The protons and neutrons are in the nucleus and the electrons orbit around the nucleus.
Does this atom have a positive charge, a negative charge, or is it neutral?
It has a negative charge (it has more electrons than protons).
Does this atom have a positive charge, a negative charge, or is it neutral?
It has a positive charge (it has less electrons than protons).
Does this atom have a positive charge, a negative charge, or is it neutral?
It's neutral (It has the same number of protons and eletrons).
What type of electricity is this? (Static electricity or electrical current?)
Electrical current
