What are the main uses of electricity in our homes?
Residential uses : A significant amount of the total electricity produced globally is used for household purposes. It is used for computing, water heating, television, refrigeration, cooking and lighting, among others.
What are the advantages of electricity?
Electricity can be used to heat either storage or continuous flow water heaters, and can also be used as a booster to solar or heat pump water heating systems. The advantage of electricity is its reliable supply.
What are the 2 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. Batteries produce direct current.
What are the disadvantages of electricity?
High cost of designing and building nuclear power station.
- Waste in the form of used fuel rods which are very hot and highly radioactive.
- Hot water discharged causes thermal pollution to the environment.
- Risk of accidents which may lead to the leakage of large amounts of radioactive substances to the environment.
- A spark of static electricity can measure thousands of volts, but has very little current and only lasts for a short period of time.
- Lightning is a powerful and dangerous example of static electricity.
- As dangerous as lightning is, around 70% of people struck by lightning survive.
Does a turned off TV still use electricity?
Any appliance that has a LCD panel, light or clock, such as your DVD or DVR player, cable box, television or microwave are still consuming electricity, even when they are off. The majority of televisions, cable boxes, monitors and computers will do this, rather than turning off completely.
How do houses get electricity?
Here’s how electricity gets to your house: Electricity is made at a generating station by huge generators. The electrical charge goes through high-voltage transmission lines that stretch across the country. It reaches a substation, where the voltage is lowered so it can be sent on smaller power lines.
What is electricity made up of?
Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons.
What are 3 things that electricity can do?
Electricity carries electrical energy and, as you have seen, electrical energy can change into other forms of energy. Electrical energy can change into light energy when it flows through a lamp. It can change into heat energy in an electric toaster. It can also change into other forms of energy.
