Question

A stranded conductor of four strands,each of radius 'r' is given below.What is the percentage decrement in self distance of conductor if stranded conductor is converted into its equivalent solid or single strand conductor

Answer 1

In the above relation you can see that area of the conductor and resistance are inversely proportional. Hence if area of the conductor of increased, resistance of the conductor decreases, therefore losses (copper loss) decreases. This is the relation between conductor size, voltage and current. mark as brainlist
