1.A. You've assembled the following components to join two copper conductors: a mould, powdered copperoxide, powdered aluminum, and an igniter. With these components, which of the following processes will you use to connect the conductors? A. Exothermic welding B. Irreversible compression grounding C. Mechanical grounding D. Thermal cycling 1.B. Two electricians are discussing voltage ratings. Electrician A says that a motor that's installed 40 feet from a power source will show a lower applied voltage than a motor that's installed 20 feet from the same power source. Electrician B says that an exact voltage of 240 V must be applied to a motor that's rated at 240 V. Who is correct? A. Neither Electrician A nor Electrician B is correct. B. Only Electrician A is correct. C. Only Electrician B is correct. D. Both Electrician A and Electrician B are correct.
