ASSEMBLING AND TESTING OF A SIMPLE ELECTRIC CIRCUIT
- ASSEMBLING AND TESTING OF A SIMPLE ELECTRIC CIRCUIT.
Aim :
To assemble and test simple electric circuit containing source, knife switch, fuse and a load.
APPARATUS REQUIRED:
| Sl no | Name of Apparatus | Type | Specification | Qty |
| 1 | Fuse unit | Kitkat | 5A,240V | |
| 2 | Load (Bulb) | Clear bulb | 60W,240V | |
| 3 | Knife switch | SPST | 5A,240V | |
| 4 | source | Single phase | 5A,240V |
THEORY:
A basic electric circuit contains a source of electric energy, a load which changes electric energy into a useful form of energy and the switch control the energy delivered to the load.
Source: Source is a device which supplies the electrical energy used by the load. It any consists of a simple dry cell, a storage battery or a power supply.
Load: The load is any device through which an electric current flows and which converts their electrical energy into a more useful form.
eg: Bulb, Electric motor etc…..
Switch: It permits control of electrical device, interrupts the current delivered to the load.
The bulb does not glow when switch is open. There is no complete path for current through the circuit. But the switch is closed, the path is complete and current flows from the positive terminal to the negative terminal of the supply. Current will continue to flow until the switch is moved to open position.
PROCEDURE:
Assemble the circuit as shown in the connection diagram .Then the switch is closed and observe the output.
