Answer 2

To draw:

A neat labelled diagram of a simple electrical circuit.

Solution:

Open circuit:

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

Closed circuit:

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

The main components of a simple circuit:

• Battery (combination of cells)

• Resistance (or bulb)

• Connecting wires

• Voltmeter (for measuring potential difference across the circuit)

• Ammeter (for measuring current in the circuit)

No, the bulb will not glow , if the switch is kept open . This is because

• The circuit will not be closed.

• As a result, Current will not flow through the bulb and hence , it will not glow.
