1 Symptoms are due to the effects of excess acetylcholine on nicotinic and muscarinic acetylcholine receptors in the CNS, at neuromuscular junctions, and in the sympathetic, and parasympathetic nervous systems. 2  Nicotinic and muscarinic receptors have different. 3  Functions.
We're taking here about mains voltage (say 120 V or 230 V AC) power supplies with power ranging from a few Watts to several hundred Watts. Switch mode power supplies are everywhere; here are some pictures of their guts. The big high power components and small heat sinks are typical of SMPS. These devices are incredibly reliable, but being very often left powered all the time (even when their load is switched off), they still are the weak link.
How Hot Is Lightning? Technically, lightning is the movement of electrical charges and doesn't have a temperature; however, resistance to the movement of these electrical charges causes the materials that the lightning is passing through to heat up. If an object is a good conductor of electricity, it won't heat up as much as a poor conductor.
