Question

What is a fixed resistance?

Answer 1

Hint: Resistance may be a measure of the opposition to current flow in a circuit . Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Insulators: Materials that present high resistance and restrict the flow of electrons.
Complete answer:
Fixed resistance is named resistor, because we will change it's value consistent with our need to fix it. But rheostat may be a resistor during which resistance is often varied and consistent with our need so it isn't fixed but a variable resistance.
A resistor may be a passive two-terminal electrical component that implements electric resistance as a circuit element. In electronic circuits, resistors are wont to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. The resistor's ability to scale back the present is named resistance and is measured in units of ohms (symbol: Ω).
Resistor types
• Fixed resistors. The fixed resistor type is the commonest resistor, when people mention a resistor they most likely mean a hard and fast resistor.
• Variable resistors
• Thermistors
• Varistors
• Light dependent resistors
Resistors are used for several purposes. A couple of examples include delimiter current , voltage division, heat generation, matching and loading circuits, control gain, and fixed time constants. they're commercially available with resistance values over a variety of quite nine orders of magnitude.

Note: Fixed resistors are one sort of linear resistor. A resistor is claimed to be a hard and fast resistor, if its value is fixed. The worth of a fixed resistor cannot be varied, sort of a rheostat as its value is decided at the time of producing itself. The subsequent figures represent the symbol of a hard and fast resistor.
