14. A machine requires 10kW of electrical power when operating at 100V.

14. A machine requires 10kW of electrical power when operating at 100V. (a) If power is delivered through a cable with resistance 10002, how much power is lost to the cable's resistance? (b) In order to reduce power loss, a transformer is used between the cable and the machine. What ratio of turns is required on the transformer in order to reduce power loss on the cable by a factor of 104? [2] [2]
