Umm, shouldn't that be NTC ?

Plus heat = plus ohms in a PTC and an NTC is the opposite.

Or has my brain been screwed up all these years ?

(shaddap)

Or is this new math where positive is negative, kinda like the government's estimates of unemployment and inflation ?

In a TV (telly for y'all on the otheer side), the NTC degaussing thermistor was in series going to the (must obviously be full wave) rectifiers from the transformer. The ddegaussing coild was across the NTC thermistor. (in the old tube/valve sets)

Later, they did switch to PTC thermistors and fed the coil right off the mains. That was a PTC.

This is not the only place I noticed this error.

It might be kinda importat because if you put a PTC in series with the primary of the transformer, as it heats up it is going to raise in resistancve and give the transforme and get even hotter and give the transforme less power and get even hotter to the point where it is hardly conducting at all.

Bottom line, Ppositiv Temperature Coefficient = hotter is more resistonce or less ? It really does make a difference.
