How does it work?
Electricity is an integral part of our daily lives. We rarely think about it until it’s time to pay a bill, or it goes out. How does it work? We tend to not think about it because we cannot see it.
Electricity has positive and negative charges. Protons carry positive charges, and neutrons carry negative charges. Electric currents are the electric charges carried from electrons as they jump around from atom to atom. Copper wires or any metal wires are great conductors of electricity. They allow electricity to move and they transmit electrical energy. Subatomic particles carry electric charges. Like charges repel, and unlike charges attract. When particles carry the same type of charge, they exert a forceful repulsion.
How does one measure electrical currents?
The SI unit for measuring an electrical current is the ampere. It measures an electrical charge at the rate of one coulomb per second. The best Electricians use professional tools to help them test the strength of these by using a Phase Angle Meter.
The pressure that pushes electrons through a wire. It measures the potential energy to cause a current in an electrical conductor.
Any movement of an electrical charge.
The rate which electrical energy is consumed in a circuit.
Measures how the material reduces the electric current flow through the device that the electricity is going through.
The current through a conductor between two points is directly proportional to the voltage across two points.
Direct current (DC current)
DC current is used in low voltage applications like battery charging, automotive and aircraft function, and low current operations. For professional electricians, they use hight quality measurement equipment from only the best retailers online.
Alternating current (AC current)
Alternating currents are used to power homes, offices, buildings, etc. Understanding how electricity works, and how it fits into our lives helps us make decisions such as what kind of generator to use for our homes or buildings. Knowing what works can save us from potential inconveniences in the future.
