QI/ True or False, correct the false if exist. 1- In SRM motors, reluctance torque is produced by the tendency of the rotot to move to its maximum reluctunce position 2- Hybrid stepping motors combine aspects of both permanent magnet and cupper winding technologies. 3. In Single-phase half-wave ac valtage controller, a single pulse is enough to operate the converter for a complete electrical cycle 360. 4 In single-phase cycloconverter, if there are 4 input electrical cycles then there have to he 2 tops and 2 bottoms in the output electrical cycle. 5- In Single-phase full-converter drives of DC motors, during regeneration for reversing the direction of power flow, the back emf of the motor can he reversed by reversing the field coil terminal connections. 6- In ac generators, regulating the rpm of the rotating magnetic field controls the magnitude of the voltage produced. 7- A regulated DC power supply cannot maintains the output voltage constant if there are fluctuations in ac mains or load variations. 8- A wound-rotor induction motor is designed to have a High-rotor resistunce so that the running efficiency is high and the full-load slip is low. 9- Mix phases operation mode of stepper motor is better than one phase operation 10- In power control of DC-DC converter drives, the dissipated in rheostat

TRUE or FALSE? Correct if FALSE
1. There is no way to expand an economy using fiscal policy
without incurring (or increasing) a budget deficit.
2. The existence of budget deficits must mean that the
government is conducting an expansionary fiscal policy.
3. When a government finances its expenditures by printing money
rather than collecting taxes, this can lead to “too much money
chasing too few goods” and hyperinflation.
