Electrical and Electronics Technician Interview Questions and Answers

An encoder is a device used to convert information from one format to another, typically used in electronics to convert analog signals into digital signals.

• Encoders are commonly used in robotics to track the position of motors and other moving parts.

• There are different types of encoders such as optical encoders, magnetic encoders, and rotary encoders.

• Encoders can provide feedback for closed-loop control systems to ensure accurate positioning.

• They can also be used in communica...read more

NO NC stands for Normally Open Normally Closed, referring to the state of a switch or relay when not activated.

• NO NC refers to the two possible states of a switch or relay: Normally Open (NO) and Normally Closed (NC).

• In a NO state, the circuit is open and no current flows. In a NC state, the circuit is closed and current flows.

• NO NC configurations are commonly used in control systems and automation.

• Examples include NO NC push button switches, NO NC relay contacts, and NO NC l...read more
