In which decade was the American Institute of Electrical Engineers (AIEE) founded?

The word "laser" is actually an acronym for light amplification by stimulated emission of radiation. Atoms or molecules of the active medium that have been excited to a higher energy level are stimulated by a passing photon to relax to a lower energy level and emit a photon that is indistinguishable from the passing photon, thereby increasing the number of photons like the incident one.

This voltage often remains in storage even if the set is unplugged. Although the voltage is very high it has very low power but it can be dangerous because your body jumps if brought in contact.

PAL and SECAM are standards used in other countries. RGB stands for red, green, and blue - the colors of light used to create an image in a color tv set and is often used as a format name for computer monitors.

Twisting the yoke will tilt the picture. A projection color television uses three picture tubes and yokes for red, green and blue light.

Some authorities are recommending TV's, VCR's and Stereo's be connected to power strips with switches and turned off when not in use to save energy. Your remote will not work until power is switched back on.

The transformer is used to transform a medium voltage supply to a low voltage supply, e.g. from 11 000 V to 400 V. A transformer is rated in kVA, kilo-Volt-Amps, which is a measurement of electrical power.
