Electronic Test Engineer Interview Questions and Answers

AC and DC differ in the direction of current flow and the nature of the current.

• AC stands for alternating current, which changes direction periodically, while DC stands for direct current, which flows in one direction.

• AC is commonly used in household appliances and power distribution, while DC is used in batteries and electronic devices.

• AC voltage can be easily converted to different levels using transformers, while DC voltage remains constant.

• AC is more efficient for long-di...read more

There are various types of motors used in different applications, such as DC motors, AC motors, stepper motors, and servo motors.

• DC motors: Direct current motors that convert electrical energy into mechanical energy.

• AC motors: Alternating current motors that are commonly used in household appliances and industrial applications.

• Stepper motors: Motors that move in precise increments or steps, commonly used in robotics and automation.

• Servo motors: Motors that use feedback to con...read more
