Answer 1

$\sf{\huge{\underline{\green{Answer :-}}}}$

A path through which a current flows is known as the circuit .

It consist of bulb , switches , batteries , ammeter , voltameter etc. The current flows through a circuit in convectional or electronical way.

The circuit helps to flow the current steadily to reach a device .

Closed circuit :- The path through which current flow is possible due to joint circuit.

$\setlength{\unitlength}{1.5cm}\begin{picture}(8,2)\linethickness{0.4mm}\put(8,1){\line(1,0){0.5}}\put(10.4,1){\line(1,0){0.6}}\put(8.7,1){\line(1,0){1.2}}\put(8,1){\line(0,2){2}}\put(11,1){\line(0,3){2}}\put(8,3){\line(3,0){1.3}}\put(9.7,3){\line(3,0){1.3}}\put(8.5,0.7){\line(0,1){0.5}}\put(8.7,0.8){\line(0,1){0.3}}\put(9.7,1){\sf{\large{ \bigg(}}}\put(10.2,1){\sf{\large{ \bigg)}}}\put(9.5,3){\circle{0.4}}\put(9.4,2.9){\line(3,2){0.3}}\put(9.6,2.8){\line( - 2,3){0.2}}\put(8.1,1.1){\sf{ + }}\put(8.7,1.1){\sf{ \large{ - }}}\put(10.18,1){\circle*{0.1}}\put(8.5,0.2){\sf{ \large{Closed circuit }}}\end{picture}$

Open circuit :- The path through which current flow is not possible due to adjoint circuit.

$\setlength{\unitlength}{1.5cm}\begin{picture}(0,0)\linethickness{0.4mm}\put(8,1){\line(1,0){0.5}}\put(10.4,1){\line(1,0){0.6}}\put(8.7,1){\line(1,0){1.2}}\put(8,1){\line(0,2){2}}\put(11,1){\line(0,3){2}}\put(8,3){\line(3,0){1.3}}\put(9.7,3){\line(3,0){1.3}}\put(8.5,0.7){\line(0,1){0.5}}\put(8.7,0.8){\line(0,1){0.3}}\put(9.7,1){\sf{\large{ \bigg(}}}\put(10.2,1){\sf{\large{ \bigg)}}}\put(9.5,3){\circle{0.4}}\put(9.4,2.9){\line(3,2){0.3}}\put(9.6,2.8){\line( - 2,3){0.2}}\put(8.1,1.1){\sf{ + }}\put(8.7,1.1){\sf{ \large{ - }}}\put(8.5,0.2){\sf{ \large{O{p}en circuit }}}\end{picture}$
