Put the resistor symbol ie zig zag. Then put a crossing line with arrow headed at the top.
Resistance = R.
Scroll down to related links and look at "Symbols for a resistor".
Use the standard resistor symbol and then place an arrow across the resistor. The bottom of the arrow midpoint of the resistor and just below, the tip of the arrow (draw with an arrow head) just above the resistor. This represents the wiper of the variable resistor.
A: If you know the total resistance and total voltage then you know total current flow for the circuit, this current will be same for every resistor in series however the voltage drop will change for each resistor . So measuring the voltage drop across the resistor in question and divide by the total current will give you the resistor value.
A resistor is a material that attenuates the current through a conductor. An insulator isolates the conductor from the surrounding material.
Need more information - a typical regulated power supply would include dozens of resistors, each for one of several different reasons. Which resistor are you asking about?

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: --------->|-------
An LDR is a Light dependent resistor.
Its a sign of resistor with a tilted arrow.
symbols of fixed resistors
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.

Do not confuse 'resistance' with 'resistor'. 'Resistance' is a quantity, wheras a 'resistor' is a circuit component. In schematic diagrams, the 'rectangular' (European) or 'zig-zag' (US) circuit symbol represents resistance, not a resistor. The circuit symbol, therefore, is used to represent anyresistive device.
A "pull-up" resistor is a resistor used to to perform a specific electronic function - it is not a different type of resistor. A very small current flows through a pull-up resistor so it does not need to be high wattage (1/8 watt is generally fine). The value of a pull-up resistor depends on the resistance of the sensor. If it is simply on or off (no resistance) then a typical pull-up resistor might be 10k ohms.
