100
The flow of charge through a conductor
What is electric current
100
current = voltage/resistance
What is Ohm's Law?
100
Carry a positive charge.
What are protons?
100
The three parts of an atom.
What are the neutrons, protons, and electrons?
100
The first man on the moon.
Who is Neil Armstrong?
200
A closed conducting loop trough which electric currents flow.
What is circuit?
200
A circuit with only one path for the electric current to flow.
What is a series cicuit?
200
Carry a negative charge.
What are electrons?
200
These can be found in the nucleus of a cell.
What are neutrons and protons.
200
The first woman in space.
Who is Sally Ride?
300
A measure of how much electric energy an electron in a circuit can gain from a battery.
What is voltage?
300
A circuit that has more than one path for the current to flow.
What is a parallel circuit?
300
Carry a neutral charge.
What are neutrons?
300
The part of the atom is found outside the nucleus.
What are electrons?
300
He played golf on the moon.
Who is Alan Sheppard?
400
A measure of how difficult it is for electrons to flow through a material.
What is resistance?
400
The unit used to measure power.
What is the watt?
400
A material that allows electrons to move more easily; metals are the best kind.
What are conductors?
400
These form when atoms lose or gain electrons and become positively or negatively charged.
What are ions?
400
The first satellite in space.
What is Sputnik?
500
If you increase the resistance, what happens to the energy flow?
What is decreases?
500
This happens to the current in a circuit when resistance increases.
What is it decreases?
500
A material through which electrons to not flow.
What is an insulator?
500
The periodic table is arranged by atomic number. The atomic number is the number of these in an atom.
What are protons?
500
The oldest person to travel in space.
Who is John Glenn?
