The correct answer to this question is "Yes." A stretched spring and a box on a high shelf both have potential energy. P<span>otential energy is energy reserved to do work. </span><span>Potential energy</span><span> </span><span>stored as a result of deformation of an elastic object, such as the stretching of a</span><span> </span><span>spring</span><span>. It is equal to the work done to stretch the</span><span> </span><span>spring</span><span>, which depends upon the</span><span> </span><span>spring </span><span>constant k as well as the distance stretched.</span>
Making a wire thicker has the same effect as making a road wider. It makes it easier for the electron traffic to flow. The resistance decreases, and the current (traffic) increases.
