Electricity Basics
The subatomic particles that move in order to produce electricity.
What are electrons?
A lightbulb is an example of this type of electric circuit component.
What is an electrical load?
The formula for calculating current, if voltage and resistance are known.
What is I = V/R?
The two types of circuits that must be considered when analyzing Kirchhoff's laws.
What are series and parallel circuits?
Wires are wrapped with this material to prevent electric shocks.
What is an insulator?
The unit for resistance.
What are Ohms (Ω)?
A switch position that allows electricity to flow through a circuit.
What is a closed switch?
The voltage across a lightbulb with a current of 5A and a resistance of 2Ω?
What is 10V?
The voltage across each resistor in a circuit that contains three (3) resistors in parallel to each other and connected to a 9V battery.
What is 9V?
The process used to generate electricity.
What are electric generating stations?
The unit used to describe 6.25 x 10^18 electrons.

What are 2 factors that impact the resistance of a material?
What is the type of material?
What is the cross-sectional area?
What is the length?
What is the temperature?
The law that states that the total voltage supplied by the source must equal the total voltage used by all of the loads in that path.
What is Kirchhoff's voltage law for series circuits?
A negative effect following the burning of fossil fuels.
What is carbon dioxide release?
The rate of movement of Q.
What is electric current?
A connector in a circuit that is designed to open the circuit if there is too much current.
What is a fuse?
The current through a resistor with a voltage of 7.2V and a resistance of 3.4Ω.
What is 2.1A?

The difference in the amount of energy Coulombs have on both sides of a source or load.
What is electric potential energy?
What is voltage?
A device used to measure something in a circuit that is connected to the circuit in parallel.
What is a voltmeter?
The shape of a V vs. I graph representing a non-ohmic load.
What is non-linear?
The process of using both Ohm's law and Kirchhoff's laws to determine the voltage, current, and resistance of all loads in a circuit.
What is circuit analysis?
What is solving circuits?
The full name of the scientist who developed Ohm's Law.
