Suppose that the machining operation requires 1 kw that the


A drilling machine is driven by a single-phase induction motor connected to a 110-V rms supply. Suppose that the machining operation requires 1 kW, that the tool machine ihas 90 percent efficiency, and that the supply current is 14 A rms with a power factor of 0.8. Find the AC machine efficiency.
