Why is it desirable that the ammeter terminals be made of heavy metal and gave birth to the voltmeter terminals tend to be much lighter and well insulated?

Portions of the area and volume and to reduce the resistance of the conductor, giving the current "soft" path to flow in. Do not want to introduce some resistance on the road would reduce the Current natural flow that is trying to measure. current needs very little or nothing to be developed to measure a strain on all that matters is a good contact point a continuous conductor. ie device physics to determine its optimum form.
