Answer 2

Answer:

1- Drawings for electronic circuits are called "circuit diagrams". Drawings for electrical circuits are called "wiring diagrams".

2 -We know that the needle of a compass is a tiny magnet, which points in north-south direction. When we bring a magnet close to it, the needle gets deflected. ... So, when electric current passes through a wire, it behaves like a magnet. This is the magnetic effect of the electric current.

3 -A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.

4 -Battery.
