Q1: What is the basic idea behind a working circuit??

[Answer]

An electrical circuit is a loop that connects all of the parts without a break.

It's as simple as that.

The way the parts and the wires are arranged doesn't matter, so long as there is a loop of connected parts.

Sounds simple – but lots of people forget this rule and wonder why things don't work!
