This is the unit for the measure of number of positive and negative charge.
What is the coulomb?
This is defined as the flow of positive charges from the positive end to the negative end of a power source. Electrons flow in the opposite direction
What is current?
These materials allow electricity to move through them easily.
What are conductors?
This law is the fundamental relationship between voltage, current, and resistance.
What is Ohm's Law?
In these circuits, components connected by one end. Current is the same between all components, however voltage is split amongst them depending on resistance
What is series?
This is the unit for current, also described as coulombs per second. It is a rate, a measure of charge over time.
What is the amp? (Or ampere)
This type of current is the constant and direct flow of current in one direction( + -> -). Commonly seen in batteries.
What is direct current?
These materials hinder or completely stop the flow of electricity.
What are insulators?
This is Ohm's Law.
Voltage = current x resistance
V = I x R
In these circuits, components are connected at both ends, voltage is the same but current is split
What is parallel?
This is the unit for the potential difference between two points, positive minus negative or negative minus positive, also described Joules/coulomb.
What is the volt?
This is the type of current that is th alternating flow of current that periodically changes. Can take different shapes (sin wave, square, etc.) Seen in wall outlets.
What is alternating current?
Copper, gold, silver, and sea water are examples.
What are conductors?
This is the "R" in Ohm's law.
What is resistance?
In a circuit like this, a portion of wire in the circuit is disconnected, not allowing current to flow from + to - end.
What is an open circuit?
For Science Olympiad, we use only this kind of current.
What is direct current?
What are insulators?
This is the V in Ohm's law.
What is voltage?
In this circuit, there are no breaks in wire, current is flowing through from + to -
What is a closed circuit?
Electrons only move when there is a difference in charge between two different locations. This is that difference.
What is the potential difference?
This is the I in Ohm's Law.
What is current?
This is a circuit with low/no resistance. Can create a surge in energy and extreme heat (not good)
What is a short circuit?
