Current Electricity | Temperature Dependence of Resistivity All the best! 1. We use alloys for making standard resistors because they have- low temperature coefficient of resistivity and high specific resistance high temperature coefficient of resistivity and low specific resistance low temperature coefficient of resistivity and low specific resistance high temperature coefficient of resistivity and high specific resistance None 2. Pieces of copper and of silicon are initially at room temperature. Both are heated to temperature T. The conductivity of both increases both decreases copper increases and silicon decreases copper decreases and silicon increases None 1 out of 2 Time's up
