Sense in electronics is like being able to understand what's happening in your favorite cartoon. You know when something is happening by looking at the pictures and listening to the sounds. In electronics, it's the same way. Sense is like having special gadgets that can see and hear what's happening inside a circuit or machine. These special gadgets can tell us if the circuit is working properly or if there's something wrong. Just like how you can tell when your favorite cartoon is running smoothly or when there's a problem with the picture or sound. Sensing in electronics is important because it helps us to make sure everything is running smoothly and to fix any problems that might occur.
