Understanding the concept of electricity is very daunting for everyone, including homeowners. With electricity being the lifeline of almost all devices we use in our home, you need to know how it works. It is when you understand the electricity concept that you will be able to improve your safety and that of your home.
There are several basics things that you need to know about electricity. Most of these basics help in enhancing better use of electrical energy in your home. In this guide, we have put together crucial electricity basics everyone should know:
What is Electricity?
Defining electricity is probably one of the most difficult questions for most people. Electricity is simply the flow of electric charge in a circuit to the receptor. The charge is created by the movement of electrons, which can be utilised for doing various works such as lighting, powering appliances, and other electric devices. Therefore, electricity is simply a flow of electric charge that is created by the movement of electrons.
How is Electricity Generated?
Electricity generation remains one of the most confusing things for most people. What you may not know is that there are two main ways that electrons are generated to produce an electrical charge. They include magnetic and solar generation.
The magnetic electricity generation is the most widely used method across the world. This is where a coil of wire is rotated within a magnetic field to produce a flow of electric charge. So you need a coil and magnet to generate electricity. The set up for the two (magnet and coil) differs since either of them could be rotating. A good example of this type of electricity is the turbine set up, where a force is used to rotate the turbine to produce electricity. Geothermal, hydro, and diesel power generating plants produce this type of electricity.
Solar electricity uses photovoltaic solar panel to convert sun rays into electricity via the electronic process. The electronic movement for the PV solar panels can be used directly on the appliance and other electronics. However, the solar power system produces direct current (DC); hence you might need an inverter to change it to AC. However, the biggest disadvantage of solar electricity is that it only produces during the day when there is sunlight. So, you might need batteries for storing harvest energy for night use.
There are many terminologies used in the electrical system, some of which are also very common in our homes. You need to understand these terms because they affect your electricity use. These terms will also help you make the right decision when buying appliances and other electronic devices. They include:
Watt is one of the terms that you will find on all appliances and electronic devices in your home. It is usually a number or a set of numbers that end with “W,” e.g., 800W. Watt is the base unit of electrical power. They are used as a measure of the electrical energy that is released per unit time in a specific system. For instance, an appliance that is rated 800W means that it consumes 800 watts per hour. Note that energy bills are charged per kilowatt-hour (kWh).
Therefore, if you are looking to a hot water heater that will not consume a lot of electrical energy, you need to check the wattage rating. The lower the wattage rating, the less energy the water heater consumes to heat water.
If you look at the label in all appliances and electronic devices, you will notice the “V” signs. It is the voltage that the devices use. Voltage is simply the power that is needed to move electrons along the circuit. Most appliances in our homes use 240 or 120 volts. That’s the standard volt for homes, and thus any device you buy must be within this range.
Amperes, abbreviated as A, is the measure of the rate of electricity flow or the electric current. Every appliance requires a certain electricity flow to operate properly. Because of the possible power surges, electricity flow can increase beyond the safe levels for the appliances. That’s why we have different circuit breaker ratings for various electrical circuits. So, depending on the amperes rating of the appliance, you need a circuit breaker that will protect it from power surges.
Ohms may not be common on the most appliance, but it could help you when determining other electrical variables. It is the rate of resistance in an electrical system. If you want to reduce the flow of electrical current, you just need to add resistance to the circuit.
These are some of the electricity basics that every person should know about. All terminologies are very crucial since they will greatly determine the choice of the appliance and electronic devices you buy.
