Question

A potentiometer consists of a fine wire
wound on a circular former whose inner
diameter is 3cm. The maximum number of
turns that can be wound on the former is
250per
cm.
Calculate the percentage
resolution of the potentiometer​

Answer 1

Explanation:

The resolution or adjustability is a result of the pot geometry, dimensions element materials and construction and wiper design, the number of turns is not directly related - for example a trimpot with 20+ turns may have no better resolution or adjustability than a single-turn trimpot with similar electrical element length.
