Mobile Repairing Application” Electricity a form of energy occurs from the flow of electrons or negatively charged particles. Electricity is all about making electromagnetic energy flow around the circuit so that it will drive something like an electric motor or a heating element, powering appliances such as kettles, toasters, and bulbs.
Mobile Repairing Application” All electric circuits require two wires to operate. Electricity required a return path back to the original source. This is why a battery has two terminals and an ac voltage source has also two wires called phase and neutral.
Mobile Repairing Application of Electricity & Electronics
Mobile Repairing Application” Electronics is a much more subtle kind of electricity in which tiny electric current flows through complex? Circuits? to process signals or store and process information. An electric signal is simply an electric current or voltage modified in some way to represent information, such as sound as sound, numbers, letters, or computer instructions.
Mobile Repairing Application” There are two very different ways of storing information known as analog and digital. Generally, most modern forms of electronic equipment including computers, cell phones, digital cameras, digital radios, hearing aids, and televisions use digital electronics. electronics is used in following fields.
Telephones, Computers, Radio, Television, Cellular phone, Fax Machine.
Medicine and research:-
X-rays Machines, Hearing Aids, CT scan, Electronic Microscope.
Refrigerators, washing machines, toasters, coffeemakers, lawn sprinklers, and many other products, can turn on and off automatically. Many automobiles have electronic controls in engines and fuel systems.
Electrical and Electronic Safety:-
Please follow these general guidelines pertaining to electrical safety.
- Turn off power and unplug from the wall before working on electric or electronic circuits, except when absolutely Necessary.
- Do not use extension cords as a permanent power source.
- Do not work on electrical equipment in a wet area or when touching an object that may provide a hazardous earth ground path.
- Turn off power and unplug equipment before checking or replacing fuses. Locate and correct the cause of a blown fuse or tripped circuit breaker before replacing the fuse or resetting the circuit breaker.
- Replace defective cords and plugs. Inspect cabling for defects such as frayed wiring, loose connection, or cracked insulation.
- Remove metal jewelry, watches, rings, etc., before working on electrical circuits.
- Always check the electrical ratings of equipment you use and be sure you use that equipment within its ratings.
- Never overload circuits.
- Never leave unprotected systems unattended.
- Never place containers of liquid on electrical systems.
- Never defeat the purpose of a fuse or circuit breaker. Never install a fuse of higher amperage rating then that specifically listed for your circuit.
- Make sure equipment chassis or cabinets are grounded. Never cut off or defeat the ground connection on a plug.
- Safely discharge capacitors in equipment before working on the circuits.
