Q3. What is no and nc
Ans. 
NO (Normally Open) and NC (Normally Closed) refer to relay contact states in electrical circuits.
• NO contacts are open when the relay is not energized, allowing current to flow only when activated.

• Example: A light switch that turns on a light when pressed is a NO contact.

• NC contacts are closed when the relay is not energized, allowing current to flow until activated.

• Example: A safety switch that cuts power when triggere...read more
