Stun gun vs. electrical outlet Stun guns generate a high-voltage, low-amperage (3 milliamps) electrical charge. This means that the charge has a lot of pressure behind it, but not that much intensity. demonstation a typical household circuit can deliver 15 to 20 amps (15,000 – 20,000 ...

The first three generations were characterized by significant technological breakthroughs in electronics—the use of vacuum tubes, then transistors, and then integrated circuits. Some people prefer to consider the start of the fourth generation as 1971, while some others argue that if we accept this ...
