Basic Electricity Terms
| Alternating current (AC) | Electric current that reverses directions at regular intervals. |
|---|---|
| Electricity | The flow of electrons. |
| Electron | A negatively charged particle that orbits the nucleus of an atom. The flow of electrons produces electricity. |
| Energy | The ability to do work. Energy = Power x Time |

What does Joule mean?
Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.
What is alacrity mean?
: promptness in response : cheerful readiness accepted the invitation with alacrity.
What is a good definition for electricity?
1a : a fundamental form of energy observable in positive and negative forms that occurs naturally (as in lightning) or is produced (as in a generator) and that is expressed in terms of the movement and interaction of electrons.
What does R mean in electricity?
R is the resistance of the resistor in ohms (Ω). V is the voltage drop on the resistor in volts (V). I is the current of the resistor in amperes (A).
How do you describe electricity?
There are two basic forms of electricity: current electricity and static electricity. Current electricity (alternating current) is the energy that flows through wires in our homes and powers our lights, televisions, computers, and appliances. Batteries also supply direct current electricity.
What are the two types of electricity?
There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction.
What is static and current electricity?
Static electricity can be defined as the electricity which is created on the surface of an object due to the displacement of negative charges. Electric current is a phenomenon created by the flow of electrons. The current is produced only in conductors as it is due to movement of electrons.
Where is electricity most used?
China consumes the most electricity of any country in the world….Electricity consumption worldwide in 2019, by select country (in terawatt hours)
| Characteristic | Consumption in terawatt hours |
|---|---|
| China* | 6,880.1 |
| U.S. | 4,194.4 |
| India* | 1,309.4 |
| Russia | 996.6 |
What are 3 examples of static?
Have you ever rubbed a balloon on your head and made your hair stand up? Have you ever walked across the carpet in your socks and received a shock from a doorknob? These are examples of static electricity.
What is the best example of static electricity?
The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons. The electrons cling to your body until they can be released. As you reach and touch your furry friend, you get a shock.
What is a real life example of static electricity?
When clothes dry in a dryer, they RUB together, creating STATIC CHARGE. When sheets of fabric softener tumble with the clothes, they act as CONDUCTORS, allowing ELECTRONS to move around the clothes more easily. Static electricity can be both annoying and dangerous.
What are 4 examples of static?
To further understanding about static electricity, you should help your students to make connections between their day-to-day experiences with static electricity—such as lightning, receiving shocks after shuffling across a carpet, taking clothes that cling to each other out of the dryer, combing their hair in the …
Is Thunder a static electricity?
Have you ever wondered what causes lightning? Lightning is caused by a buildup of static electricity inside a storm cloud. Moving around inside the cloud are tiny water molecules called hydrometeors. These hydrometeors are colliding and bumping into each other—creating a static electric charge.
How do printers use static electricity?
Using static electricity, the drum attracts powdered toner from its cartridge to the drum. The drum rolls the toner onto the paper in the form of your print. The toner is melted onto the paper by heat from a fuser as it passes underneath. Your print comes out of the printer.
Can static electricity kill you?
The good news is that static electricity can’t seriously harm you. Your body is composed largely of water and water is an inefficient conductor of electricity, especially in amounts this small. Not that electricity can’t hurt or kill you.
How do you get rid of static electricity?

- Buy a Humidifier.
- Treat Your Carpets.
- Rub Dryer Sheets Over Your Upholstery.
- Stay Moisturized.
- Wear Low-Static Fabrics & Shoes.
- Add Baking Soda to Your Laundry.
Why do I generate so much static electricity?
Very dry air and cold weather increases static electricity, so static shock takes place more often in the winter when the air is especially dry. Static electricity can be embarrassing and literally a pain that wreaks havoc during the winter months. When the air is dry, static cling is everywhere.
How do I stop getting static shocks?
If you carry a metal object like a coin, key or paper clip around with you, and touch it to something metal in your house, any electrons stuck to your body will flow through the metal and away, preventing the “jumping” effect that causes a shock.
How do you discharge yourself?
Touch a metal object using another metal object to release static discharge. This allows sparks from the discharge to affect the metal object, and not your skin. For example, touch a doorknob using a key instead of your hand at first to lower the risk for electric shock.
Why do I keep getting electric shocks?
Static shocks are more common when it’s cold and dry. This dry, cold air holds less water vapour than warm summer air. So, when you touch something like a metal doorknob or car door, those extra electrons will rapidly leave your body and give you the shock.
Why do I feel a shock in my heart?
Cardiogenic shock occurs when a weakened heart is suddenly unable to pump enough blood. “Shock” means that not enough blood and oxygen are reaching the brain and other organs. The most common cause of cardiogenic shock is a severe heart attack (myocardial infarction).
How can remote workers prevent electric shocks?
If this can’t be avoided, rubber gloves and boots should be used to reduce the intensity of an electric shock. Appliances, tools and equipment used in wet areas should always be plugged into a GFCI outlet, or should be used with a GFCI extension cord which will prevent electrocution.
Will rubber gloves prevent electric shock?
Selected properly, insulating rubber gloves will do the job of protecting the worker against electrical shock. Do not forget about leather protectors, for they are an essential part of wearing and using the insulating rubber gloves correctly.
