what is the exact direction of current? as we know current travels from higher potential to lower potential,so if we take battery +ve to -ve implies current direction is from positive terminal to negative terminal.,whereas electrons flow from negative to positive as they are attracted by positive ions.current will be the plow of charge but not flow of positive ions.please clarify my doubt friends.
