Energy Sources
Gone with the "...", this source of energy is great on blustery days.
What is wind?
A circuit needs at least these three components.
What are a power source, a path (wires) and something to use the energy (e.g. lightbulbs)?
Ohm's Law states that voltage is equal to this.
What is current multiplied by resistance?
A type of energy that comes from the movement of electrons
What is electricity?
This type of material allows electricity (or heat) to flow through it.
What is a conductor?
A source of energy coming from the sun
What is solar power?
This type of circuit has multiple lightbulbs in one path.
What is a series circuit?
In Ohm's law, current is represented by this letter, and measured in this unit.
What is "I" and "amps"?
A looped path for electrons to flow, usually consisting of a power source, wires and something that uses electricity
What is a circuit?
This type of material prevents electricity (or heat) from flowing through it.
What is an insulator?
This source of energy can be made from radioactive elements such as uranium.
What is nuclear?
This type of circuit has multiple pathways for electricity to flow.
What is a parallel circuit?
Mathematically as an equation, Ohm's law is written as this:
What is V = I x R?
(or V = IR)
This is the term for the flow of electrons in a circuit, measured in amps.
What is current?
These can be added to electrical circuits to control the flow of electrons and protect your electrical devices.
What are resistors?
This sedimentary rock used for energy comes from plant matter that didn't fully decay millions of years ago.
What is coal?
What is measures voltage?
As voltage and current increase in a circuit, this also increases in a circuit.
What is resistance?
What is voltage?
What is AC (alternating current)?
Often found in mountainous areas, this source of power converts the gravitational potential energy of water to mechanical energy to spin turbines.
What is hydropower?
If current flows along this unintended low-resistance path, it can cause a surge in electricity and "fry" your devices.
What is a short-circuit?
This is what we get if we rearrange Ohm's Law (V = I x R) to solve for R.
What is V / I? (V divided by I)
Measured in ohms, this describes the opposition to electrons flowing in a circuit.
What is resistance?
This device converts mechanical energy into electrical energy, often by moving coils of wire in a magnetic field.
What is a generator?
