Hi All
I came across a circuit where the resistors are drawn with lines in them. I have not come across this before and wondered what it meant. Are they something special? Source:- https://diodnik.com/laboratornyj-blok-pitaniya-svoimi-rukami-0-30v-0-5a/
Thanks for any help

 

A diagonal line normally indicates a thermistor or varistor.

 

Hi,
The Low resistance zig/zag indicates a wire wound resistor.
The resistor with two vertical bars could be a fusible resistor.

Guys,
it's the circuit from a russian source. They used a special marking for resistors . From about 1970 till now. As it was noted, a zig-zag mean a wire wound resistor. Two short lines across the symbol mean power rating- 2W. One diagonal line mean 0.25W resistor.
If you met two diagonal lines- it's a 0.125W resistor. One line along is a 0.5W resistor. One line across mean a 1W resistor
