Laptop Battery Chemistry 101 - Discount Laptop Batteries (Lithium Ion and Nickel Metal Hydride)
All rechargeable discount laptop batteries create an electrochemical reaction that forces a stream of electrons from one place to another, then repeats the process once an external power source forces the electrons back to their starting point. In discount laptop batteries, the trick is to find an electrochemical reaction that provides the right mix of stability, safety, sustainability, physical size, weight, charge capacity, lifespan, environmental impact, and manufacturing cost.For the laptop ...
What is Alternating Current?
In electricity, alternating current (AC) occurs when charge carriers in a conductor or semiconductor periodically reverse their direction of movement. Household utility current in most countries is AC with a frequency of 60 hertz (60 complete cycles per second), although in some countries it is 50 Hz. The radio-frequency (RF) current in antennas and transmission lines is another example of AC.More information on Alternating Current (AC):An AC waveform can be sinusoidal, square, or sawtooth-shape ...
