Capacitor allows ____ and blocks ____
- A.
AC,DC
- B.
DC,AC
Correct Answer
A. AC,DCExplanation
A capacitor allows the flow of alternating current (AC) while blocking the flow of direct current (DC). This is because a capacitor can store and release electrical energy in the form of AC, but it cannot store a steady flow of DC. Therefore, when AC is applied to a capacitor, it allows the current to pass through, while blocking the flow of DC.Rate this question:

Single phase induction motor is self starting.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Single phase induction motors are not self-starting. They require an external force to start rotating, such as a capacitor or an auxiliary winding. Unlike three-phase induction motors, which are self-starting due to the rotating magnetic field produced by the three-phase power supply, single phase induction motors need additional components to create a rotating magnetic field and initiate rotation. Therefore, the statement that single phase induction motors are self-starting is false.Rate this question:
