History of the Light Bulb
A Brief History of the Light Bulb
The electric light, one of the everyday conveniences that most affects our lives, was not “invented” in the traditional sense in 1879 by Thomas Alva Edison, although he could be said to have created the first commercially practical incandescent light. He was neither the first nor the only person trying to invent an incandescent light bulb. In fact, some historians claim there were over 20 inventors of incandescent lamps prior to Edison’s version. However, Edison is often credited with the invention because his version was able to outstrip the earlier versions because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve and a high resistance that made power distribution from a centralized source economically viable.

Whose patents formed the basis of modern AC electric power systems?
Nicola tesla
What is meant by capacitor?
A capacitor is an electrical or elctronic semi conductive material which have the ability to store electrical charge and discharge when needed, and also used for timing a circuit and finally used for filtering in a circuit. A capacitor is made up of two plates seperated by die-electric strength or material. Thanks
What circuit whose parameters change with voltage or current?
non-linear circuit
Applications of rlc circuit?
An R-L circuit is one having both resistance and inductance. These are naturally-occurring quantities that most circuits possess and, so, don't necessarily have any practical applications per se. However, a practical example of an R-L circuit is an electric motor whose windings have both resistance and inductance.
What is uncontrolled rectifier?
Uncontrolled rectification is rectification whose baise is not controlled by a gate signal.
