Question

A copper wire has a diameter of 0.5 mm and resistivity of 1.6 × 10 -8  m. (a) What

will be the length of this wire to make its resistance 10  ?​

Answer 1

resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
