Question

Boojho has drawn the inside
of the torch as in Fig. 12.11.
When we close the switch.
the circuit is completed and
the bulb glows. Can you
draw a red line on the figure
indicating the complete circuit?​

Answer 1

Explanation:

Just draw a red line above the brown one.

Answer 2

The following diagram is of a torch or flashlight.

• The circuit connects with a battery and to a bulb with a switch.
• The battery is placed in a '+' or '-' position which allows electricity to pass through. The switch when on allows the current to pass since it connects the circuit. When the switch is off, it creates a gap between the circuit due to which no current can be passed.
• The light glows in the bulb only when the circuit is on which s=means when the switch is turned on.
• To identify the right circuit connection we need to draw a line between the batteries and bulb along with a switch that connects to both ends.
