What does they mean by unwanted noise/interference in an electric path or circuit? What is unwanted noise/interference?

Expert Solution

Step 1

As we know, it is impossible to achieve an ideal situation in Physics. There are always some factors to disturb. In electrical circuits, that disturbance is noise.

Any electrical circuit obviously works with current and voltage. In simple words, we can define noise as fluctuations caused in these current and voltages. These fluctuations are not of very high amplitude but as we know disturbance is indeed a disturbance after all.

In other words we can say, electrical noise occurs in a circuit when electrical signals we are receiving produce undesirable effects.
