Answer the following with True or False and correct the error if any:Note: For the False answers, if you didn't correct the error, then the degree will be zero for it.1) If a transformer steps up the voltage level of a circuit, the current will not be affected andthe power into the device will equal the power out of it.2) The transformer that is used to step the voltage down from (110 kV) to (2.3 kV) is called aunit transformer.3) The active power is the actual power which is dissipated in the circuit.4) The flux linkage of a transformer is the sum of the flux passing through each turn in the coiladded over all the turns of the coil.5) All the flux produced in the primary coil of a transformer also passes through the secondarycoil.6) When calculating the transformer voltage regulation, the effects of the excitation branchcan be ignored, and only the series impedances need to be considered.7) The wound-rotor induction motors are rarely used, and it is not so common in industryapplications.8) For a 50 Hz, 8 pole induction motor, the synchronous speed of this motor is 650 r/m.9) A 480-V, 50-Hz three-phase induction motor is drawing 40 A at 0.8 PF lagging. if the statorcopper losses are 1800 W, and the core losses are 1050 W, then the air-gap power is22500W.10) The induced torque (Tind) in a machine was defined as the torque generated by the internalelectric-to-mechanical power conversion.
