Electric energy is acquired from the movement and transference of electrons. Learn the definition of electric energy, then discover its source in matter and atoms, explore the electron flow and its resistances, and then review examples of electric shock.

Introduction to Electric Shock Electric current passing through the body, particularlyalternating currentat power frequencies of 50 Hz and 60 Hz, may disrupt the nervous system, causing muscular reaction and the painful sensation ofelectric shock. The most common reaction is to be thrown off the con...

Electrical Relay Definition Relays are electrically operated switches that open and close the circuits by receiving electrical signals from outside sources. Some people may associate “relay” with a racing competition where members of the team take turns passing batons to complete the race. The “re...
Electrostatic discharge (ESD) is the release of static electricity when two objects come into contact. Familiar examples of ESD include the shock we receive when we walk across a carpet and touch a metal doorknob and the static electricity we feel from clothes coming out of the dryer. Lightning...
Electronic components’ dependability can be impacted by vibrations, particularly when mechanical motion or shock are present. For these situations, components with vibration-resistant properties, including reinforced leads or sturdy packaging, are preferable. ...
Batteries are common energy sources which convert chemical energy to electrical energy. They have two terminals, which connect to the rest of the circuit. On one terminal there are an excess of negative charges, while all of the positive charges coalesce on the other. This is an electric pot...
Electric shock heart damage is a very serious and potentially deadly injury that requires immediate medical attention.
Digital devices: Accelerometers in smartphones and digital cameras are used to rotate the display automatically based on the orientation in which the display is held. Vehicles: Over the years, the invention of the airbag has saved millions of lives. During a violent shock, the sensor provides...
