Tuesday, 6 January 2015
        Now we will learn about new concept called 'SuperConductors'.We will start from beginning,metals are classified into 3 types conductors,semiconductors and insulators.when voltage is applied to conductors or semiconductors,electron flow(current) occurs, and this flow is restricted by resistance which is the property of conductors.This resistance is resulted due to impurities,defects...
