Answers to Evaluation Problems 
No. 1 In a workshop two machines are driven by an electric motor
Power consumption: 
motor A = 1 KW 

motor B = 2 KW 
For a new machine of which its motor C receives the power of 4 KW, the maximum main power of Pmax = 4 KW is sufficient only if the two other machines (A and B) are not switched on. Design a circuit which supplies a warning signal Q if a power higher than 4 KW is taken from the main power system by the three machines.
