Experiment: - 6 :- Construct a simple circuit using AC/ DC supply, lamp, fuse and switch.

Constructing a Simple Circuit

Materials:

• DC Circuit: DC power supply, lamp, fuse, SPST switch, wires.

• AC Circuit: Low-voltage AC supply, lamp, fuse, SPST switch, wires.

• Tools: Multimeter.

Safety: Always turn OFF the power supply before making connections.

Part 1: Simple DC Circuit

Procedure:

1. Check Components: Use a multimeter on continuity mode to verify the lamp, fuse, and switch are functional.

2. Assemble: Connect the components in series:

   • + DC Supply → Fuse → Switch → Lamp → - DC Supply

3. Test:

   • Turn on the DC supply.

   • Close the switch to turn the lamp ON.

   • Open the switch to turn the lamp OFF.

Part 2: Simple AC Circuit

Procedure:

1. Assemble: Connect the components in series, placing the fuse and switch on the live wire:

   • Live Wire (AC Supply) → Fuse → Switch → Lamp → Neutral Wire (AC Supply)

2. Test:

   • Turn on the AC supply.

   • Close the switch to turn the lamp ON.

   • Open the switch to turn the lamp OFF.

Report & Analysis:

• Draw diagrams for both circuits.

• Explain the role of the fuse as a safety device.

• Explain the role of the switch as a control device.

• State why it's a safety best practice to place the fuse and switch on the live wire in an AC circuit.
