The average resistance of the project

Question 1 a) 600 m of wire is allocated for 5 houses. Only 450 m is delivered. How many houses can be wired completely? b) Two thirds of a project is wired using wire with resistance of. The remaining third uses wire of . What is the average resistance of the project? c) What would the resistance be if the project in b) used 50 m of wire? d) What would the length of each wire type be in b)? Question 2 Using Mesh Analysis for the circuit shown, the following two equations are obtained for the currents. Solve them simultaneously, showing your chosen method. Values to 3 s.f. Question 3 What is the voltage drop over two 12 AWG conductors (resistance of 0.20 ohms per 100 m) supplying a 16 A load located 50 m from the power supply?
