Why are fixed resisters used in many circuts?
Hi, where there is no need of changing the value of resistor then why do you place variable resistor instead a fixed resistor. After all the selection of resistor depends on the cause of use in application. by the way wide range of resistor values are avilable in the market. if the application requires tuning operation then variable resistor is need to be mounted. nothing is mandatory unless the application requires.

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 happen to the phase angle if the value of capacitor is fixed and the value of resistor is changed?
The phase angle will either go up or down as well, depending on the new value of the resistor.
What is the function of a variable resister in an electrical circuit?
A variable resistor usually has three terminals, one of which is connected to the 'wiper' by which means its resistance is measured. By using all three terminals, we can control the potential difference in a circuit. When used in this way, we call the variable resistor a 'potentiometer'. By using two of the three terminals, one of which must be connected to the variable wiper, we can control the current passing through circuit. When used in this way, we call the variable resistor a 'rheostat'.
What is the function of a cement resistor?
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
What direction does a resistor go around in an electrical circuit?
It doesn't matter which way round you place it.
Does it matter which way round a resistor is connected in the circuit?
No it doesn't
Which way round should a fence go?
Clockwise
Which way do a merry-go-round turn?
Merry-Go-Rounds spin counterclockwise.
Which way does a marry-go-round turn?
An English Merry-go-round will rotate clockwise. A French one will rotate anti-clockwise. Carousel is the preferred name.
Which way does a marry go round spin?
usually counter-clockwise.
Is a resistor the same as a diode blocker?
No... Diode block one way... resistor block eitherway.
According to a song in muscial cabaret what makes the world go around?
Money. "Money makes the world go 'round, the world go 'round, the world go 'round. Money makes the world go 'round in the most delightful way. Money, money, money, money. Give a little. Get a little."
Is the water cycle occurring same way everywhere at the same time?
The water cycle will forever go round and round.

It was a way of getting round for them as they did not have aeroplanes cars ect...
What way round should skateboard go?
it depends on if you ride goofy or regular
Which way round does a pajero thermostat go?
The side with the spring faces into the engine.
