With an illustrations, describe how DC power can be measured in a DC 2 wire circuit using the voltmeter-ammeter method in two cases. in case 1: when the voltmeter is connected near the load; case 2: when the ammeter is connected near the load. Also derive the expressions for the actual (true) resistance for the two cases.
