fixed resistors r fixed...lol
preset resistor is a type of variable resistor....u needn't know abt it for the igs
@d!_†oX!©:
ohhhh man!!!
y is it that i always end up asking question that are not needed in my syllabus??!!!!!
anyways cud u still expand a bit more nid??!!!

Preset resistors are used in circuits when it is necessary to alter the resistance. Dark/light and temperature sensors usually have these components as the preset resistor allows the circuit to be made more or less sensitive
@d!_†oX!©:
ohhhhh....as in when the use of a potential divider circuit s used??!!!
thnxx..got it....perhaps it is used with transistors and all....
soo is it a part of the A level curriculum??
