A potentiometer consisting of a uniform wire of length l and resistance R_(0) is connected to a steady voltage source of V_(0) find the voltage V supplied by it to a fixed load R as the funciton of the distance x of sliding contact from the higher potential end Analyse the case when RgtgtR_(0)

Answer»


ANSWER :V=`V_(0)(RX)/(Rl+R_(0)(L-x)x//l);V=(V_(0)x)/(l)`
