Difference between variable and fixed resistor?
Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.
The difference between fixed and variable inputs?
difference between fixed and variable inputs
What is the difference between resistor and metrosil?
Resistors are ohmic and fixed whereas metrosils are non ohmic and variable - version of a varistor.
What is the difference between fix and variable mortgages?
The difference between fixed and variable mortgages are that in a fixed mortgage, the rate can not change. In a variable mortgage, the rate changes with time.
Does a variable resistor have a bias?
A variable resistor means that the resistance can be varied, usually by using a slide. A fixed resistor can not be varied.
What is the difference between a fixed second mortgage and one with a variable rate?
The difference between a fixed second mortgage and one with a variable rate is that fixed second mortgage has a fixed rate and is commonly thought of as safer than a mortgage with a variable rate.
What is difference between fixed overhead and variable overhead?
The difference between fixed overhead and variable overhead is that fixed overheads are the ones that do not change regardless and variable overheads are the ones that vary depending on the number of units that it produces. An example of fixed overhead is a managers salary.
What determines the difference between a variable and a fixed cost?
The relataionship of cost between the level of production is determine the fixed or variable cost if cost change with production level then it is variable cost otherwise fixed cost.
List three variable resistor and list three fixed resistors?

What is the difference between variable overheads cost variance andfixed overheads cost variance?
Variable overhead cost variance is that variance which is in variable overheads costs between the standard cost and the actual variable cost WHILE fixed overheads cost variance is variance between standard fixed overhead cost and actual fixed overhead cost.
How to calculate the resistance to step down DC voltage?
Connect a variable resistance across DC source (fixed ends of variable resistor or Rheostat) and take decreased DC output across its one fixed terminal and other variable terminal of variable resistor. Other method is connect variable resistor in series with DC output and load, vary the resistance and take decreased DC voltage as required.
Why you use resistor with variable resistor?
Often we want to easily change a resistor value, so we use a variable resistor. For example, we may want to change the resistor that controls the power sent to a LED, so we can easily make it brighter or dimmer. Often if we use a variable resistor, there is only a very narrow range that is useful. Continuing our example, sometimes we use several LEDs, and we use the variable resistor to set them all to the same brightness. In this case, the resistance range that sets the LED to be twice as bright as the the other LEDs, and the resistance range that sends so much power to the LED that it is permanently destroyed is even less useful. So we add a fixed resistor in series with the variable resistor -- the fixed resistor sets the minimum net resistance, no matter how we turn the knob on the variable resistor. In our example, the addition of the fixed resistor allows us to turn the variable resistor throughout its whole range, and the LED gets brighter and dimmer; without that resistor, a certain range of the knob on the variable resistor would allow so much power to go to the LED that it would be destroyed.
