Expert Answer:

Let's take a battery and connet is across a small bulb. It glows.

Now take a small thin copper wire and connect it across the battery terminals. Immediately we see that the bulb no longer glows. Since the thing copper wire has least resistance compared to that of bulb, and by connecting it to battery terminals we have provided a least resistance path for electron flow, electric current takes the shortest route.

Thus we have short circuited the small bulb circuit.
