The trimmer resistor is a calibration device used to correct (trim) the resistance of some other resistor. An example might be the feedback loop of an op-amp in common mode. If you wanted a gain of two, you might use a resistor divider with a two to one ratio. Resistors have tolerance, however, so the stated value will not be exact. You place a trimmer resistor in series with one of the other resistors, picking the value so that, if the two other resitors were exact, the trimmer is set to midpoint, and that the trimmer's range covers the expected tolerance of the other resistors. Then you calibrate the circuit to the expected gain using the trimmer.

What is an LDR symbol?
An LDR is a Light dependent resistor.
When 2 resistors are connected in parallel r1r2 are?
Two resistors connected in parallel are 1/2 the sum of their resistance. The resistance of two resistors connected in series is the sum of their resistance. For example: The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in parallel is 100+200 divided by 2 = 150 ohms. The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in series 100+200= 300 ohms.
What is a trimmer resistor?
A trimmer resistor usually called a trim pot is a small variable resistor it is used in circuits to do preset it is trimmed with a trimmer screwdriver it is made up with a round fiber disc with a layer of carbon with a wiper that run on the carbon layer to change the resistance it always have 3 connecting pins where the center one is connected to the wiper and the other two to opposite ends of the carbon strip.

What is a function of a resistor in a smoke detector?
Resistor have a definite function in circuits and because every resistor disspates power, it is not included in the circuit without good reason. Some smoke detectors have electronic circuits in them, and these would have resistors, but it is not possible to be more specific.
