Correct option is A
A universal motor is preferred for applications that require high speed and high starting torque:
Explanation: Universal motors are designed to operate at high speeds, often exceeding 3,500 rpm, and have high starting torque. They can run on either AC or DC power, and are often built into the device they power.
Applications: Universal motors are used in many household appliances and portable power tools, including hair dryers, grinders, table fans, blowers, polishers, and kitchen appliances.
Characteristics: Universal motors are lightweight and compact, and are relatively easy to control. However, they are noisy and less suitable for continuous use because the commutator brushes wear out.
