is therea relationship between potentiometer and resistance connected in series and parallel circuit diagrams with proper relations would be much appreciated * how resistance in parallel and series will help use potentiometer in different ways

OpenStudy (aravindg):

k wel before i nswer tell me why u need this is that an assignment?

OpenStudy (aravindg):

k

OpenStudy (aravindg):

to put it short potentiometer is a variable resistor

OpenStudy (anonymous):

my question is rltnship btw potentiometer and resistance in series and parallel

OpenStudy (aravindg):

k u see wt we do in a potentiometer is that we vary the resistance this can be done in 2 ways :by using a network of series or parallel connection

OpenStudy (aravindg):

a parallel circuit reduces the effective resistance while a series increases the resistance

OpenStudy (anonymous):

how u know this much?

OpenStudy (aravindg):

srry the last sentence was a mistake

OpenStudy (aravindg):

i meant the potentiometer acts like a fan speed controller
