-----/\/\/\/\/\-----
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.

Find the symbol of fixed resistor?
symbols of fixed resistors
What are those materials of resistors?
most of the resistors commonly used are carbon resistors
Characteristics of resistor in series and parallel connection?
Resistors in series add resistance to an electrical circuit. For instance two 1 ohm resistors in series will have 2 ohms of resistance. Resistors in parallel divide the resistance between them. Thus two 2 ohm resistors in parallel will have 1 ohms total resistance. resistors of different sizes work the same way. a 4 ohm and 2 ohm resistor in series have 6 ohms resistance. While in parallel they will have .75 ohm resistance. resistance formulas: series: Req = r1+r2+r3....+rx parallel: Req = 1/r1 + 1/r2 + 1/r3 ..... +1/rx
What is carbon composition resistors?
Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. It's one type of resistors among several. There are also carbon-film resistors and metal-film resistors. Out of all the resistors, carbon-film resistors have the greatest tolerances and changes to temperature fluctations. Thus, they are used in applications where precision isn't critical and where temperature will not change drastically.
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
Who invented resistors?
Otis f.boykin invented resistors
What is the advantage of film resistors over carbon resister?
Film resistors have lower noise than carbon resistors.
Two resistors are connected in parallel to a battery What must the votlage across these two resistors?
Both resistors will have the voltage of the battery.
What are Resistors wired in series?
Resistors are wired in series when they are connected in a line. The current flows through the resistors one after the other.

What are resistors that produce a straight line graph called?
Linear resistors
What are resistors and why are they used?
Resistors are like funnels, they restrict the flow of current.
