Basics of Electricity
Known as the building block of everything, it is made up of 3 parts; protons, neutrons and electrons.
What is an atom?
This happens when two objects rub together, causing electrons to transfer from one object to another.
What is friction?
This type of material allows electricity to flow through it easily.
What is a conductor?
Demand for electricity is expected to increase by about 80 percent by this year.
What is 2050?
This is the process in which two atomic nuclei combine to form a single nucleus.
What is nuclear fusion?
In Ohm's Law, the formula that relates voltage, current, and resistance is represented as V = IR, where "V" stands for this.
What is voltage?
Electricity is the flow of this...
This sudden discharge of static electricity occurs during a storm.
What is lightning?
Rubber, glass, and plastic are examples of this type of material.
What are insulators?
Around the world, this many people do not have access to reliable electricity.
What is 1 billion?
This is the most common place where plasma is naturally found.
What is the Sun or stars?
This unit is used to measure the electrical resistance in a circuit.
What is ohms?
An imbalance of electrons
What is a charge?
Materials like rubber and plastic are known as this because they resist the flow of electrons.
What are insulators?
The human body can conduct electricity because it contains a lot of this substance.
What is water?
These energy sources, including wind and solar, are growing in popularity due to concerns about climate change.
What are renewable energy sources?
This natural light display occurs when plasma conducts electricity and emits light, often visible in polar regions.
What is the aurora borealis (or northern lights)?
According to Ohm's Law, if the resistance in a circuit increases while the voltage remains the same, this happens to the current.
What is the current decreases?
An electron in an energized state
This happens when two objects with the same charge are brought close to each other.
What is repel?
Wood is a poor conductor because it does this to the flow of electricity.
What is blocks/resists?
This is the approximate amount of electricity, in kilowatt-hours, consumed globally each year as of 2020.
What is 3 trillion kilowatt hours?
In order to achieve nuclear fusion on Earth, scientists use methods such as magnetic confinement, like the one used at this reactor in France.
What is the ITER reactor?
If the current in a circuit is 5 amperes and the resistance is 2 ohms, what is the voltage across the circuit?
What is 10 volts (using Ohm’s Law: V = IR)?
Electrons surround a nucleus in these
What are Shells?
The sudden shock you feel after walking on carpet and touching a metal doorknob is an example of this.
What is static discharge?
This common household item uses a metal filament because it needs a good conductor to produce light.
What is a light bulb?
Data centers that support AI systems contribute significantly to energy consumption because they run continuously and require this to prevent overheating.
What is cooling?
This radioactive isotope, needed for fusion reactors, is much rarer than Deuterium, which can be found abundantly in seawater.
What is Tritium?
In a simple circuit, if the voltage is 12 volts and the resistance is 4 ohms, the current would be this amount.
What is 3 amperes (using Ohm’s Law: I = V/R)?
