The internal gain of an amplifier is the gain or the amplification factor of the transistor used in it....................it is internal because it is fixed for transistors while manufacturing..................
internal resistance is always infinite in ideal current source .the internal resistance is in shunt with current source
Because many electronics, like power supplies, have internal energy storage in the form of capacitors. If you were to short the terminals, you would be shorting out the internal capacitors and thus creating a potentially hazardous situation. "Completing the circuit by internal resistance" allows the energy stored in the internal capacitors to bleed off slowly because the internal resistance is larger than a short.
the laser was invented.....
Internal Autoweld. An Internal Autoweld is a machine operated welder that is used to weld the interior seams in a pipeline.
John hopps invented the first external pacemaker. Later Earl Bakken improved this pacemaker by making it battery powered. And then Wilson Greatbatch invented the first implantable pacemaker!
the electronic pacemaker was invented by Edgar H Booth, in 1926, but it was used in 1928.

It was invented at Cornell University by Wilson Greatbatch.

Some people die when their heart beats become irregular. By installing a pacemaker, it gave them 10 to 20 more years of life.
John Hopps, a Canadian, invented the first heart pacemaker. At the age of 21, He was able to build the first pacemaker in 1950.
