The modern symbol is a thin rectangle, with the lead outs shown at the centre of the smaller ends.
The old symbol was shown as a Zigzag.
The symbol for Light-Dependent Resistor (LDR) is a resistor symbol with photo-sensitive material added to one side. It looks like a regular resistor with one side having a shaded area to represent its light sensitivity.
The symbol of a thermistor is a resistor with an arrow pointing towards it.
Scroll down to related links and look at "Symbols for a resistor".
Put the resistor symbol ie zig zag. Then put a crossing line with arrow headed at the top.
Scroll down to related links and look at "Resistor symbols".
-------------[_________]-------------- and put a line on the top of the box
The following is the closest I can get using character map: ───►├── Keep in mind that the gaps are not supposed to be there. It's just a formatting error. the symbol is like this but without the gap: --------->|-------
Its a sign of resistor with a tilted arrow.
An LDR is a Light dependent resistor.
symbols of fixed resistors
yes resistor can check in CRO.Using an probes we can check it. CRO shows the waveform.
labeled R, a resistor looks like this in a diagram-----/\/\/\/\/\-----add a variable resistor has an arrow superimposed at an angle.The modern symbol is a thin rectangle, with the lead outs shown at the centre of the smaller ends.The old symbol was shown as a Zigzag.
