Why does a shaded-pole motor run at a constant speed? a. the lines of force do not change direction. b. the current through the rotor circuit is constant. c. the inertia of the load is at a minimum. d. the frequency of the applied voltage is constant.

7. design a circuit with three inputs (x, y, and z) representing the bits in a binary number, and three outputs (a, b, and c) also representing bits in a binary number. when the input is 1, 2, or 3, the binary output should be one lesser than the input. when the input is 4, 5, or 6, the binary output should be one greater than the input. when the input is 0, the output is 0, and when the input is 7, the output is 7. show your truth table, all computations for simplification, and the final circuit.
