Ω, Sweet Ω
This is the formula for Ohm’s Law, which relates current, voltage, and resistance.
What is
V = I\cdot R
In a series circuit, if one light goes out, this happens to the others.
What is: they all go out
It’s the negative kind of pick-up line — this particle hops between objects when your sweater meets a balloon.
What is an electron
This educated guess is the starting point for many scientific investigations — and no, it’s not your horoscope.
What is a hypothesis
This is the name for the amount of electric potential energy per unit charge — basically the "pressure" behind a pushy electron.
What is electric potential (or voltage)
The resistance of a device if it draws 3 A of current when connected to a 12 V power supply?
What is 4 Ω
You walk into a physics cafe. The barista says the total resistance in series is just the sum of these. You nod, and say...
What are the individual resistances
This law of electrostatics, relating charge, electrostatic force and distance, is like Newton's lesser-known cousin — but with a shocking personality.
What is Coulomb’s Law
A well-designed experiment includes this—a sample/environment that is not exposed to the independent variable in order to gain true insight into its impact (e.g., accounts for "placebo effect").
What is a control
These lines help visualize the electric field around charges — and the closer they are, the stronger the force.
What are electric field lines
When asked "Watts up?" this Ohm's Law formula has the answer if you're measuring voltage and current.
What is P = V × I
In a shocking twist, this type of circuit allows electrons multiple paths to party.
What is a parallel circuit
Coulomb’s Law says this will quadruple if two charges stay the same but their distance is cut in half.
What is the electric force
When you change one thing in an experiment to see its effect, you're tweaking this type of variable.
What is the independent variable
This unit is used to measure electric potential
What is the volt
This kitchen appliance has a 15-ohm resistance and runs on 10 A of current. Calculate the shocking amount of voltage it consumes.
What is 150 V
The unit for this circuit-crucial quantity could also be a pirate’s cheer (but spelled differently).
What is the Ohm (Ω)
This term is used to describe any material that's considered the life of the party when it comes to spreading electric charge across its surface or allowing for the flow of electrons.
What is a (good) conductor (like copper)
This is the title you give to a scientific idea that’s backed by years of testing and hasn’t ghosted peer review.
What is a scientific theory
Due to compounding resistance, this tends to occur across resistors configured in Series
What are voltage drops
This quantity, measured in volts, drops across resistors like mic drops in a rap battle.
What is potential difference/voltage
Two resistors in series (10 Ω and 20 Ω) are wired in parallel with a single 30 Ω resistor. This is their combined resistance
What is 15 Ω
In an electrostatic paint sprayer, this change gives the biggest boost in attraction. (i.e., what variable can be changed, and how to significantly boost the attractive force between charges?)
What is reducing the distance
This scientific process involves others reviewing your work to find flaws or improve the experiment — it's not just criticism, it's collaboration.
What is peer review
Coulomb might call it a shocking secret: this is the formula for the electric field around a point charge.
What is
E = k\cdot Q/r^2
