Safety and necessary Precautions:
- Wear protective gear
- Ensure proper wiring
- Use appropriate voltage
4. Use appropriate measuring equipment
- Avoid touching the circuit
- Handle components with care
- Follow laboratory guidelines
Procedure:
1. Connect the circuit as per circuit diag.
2. Switch on the DC voltage supply, Adjust the voltage to
any suitable value.
Observations:
- KVL: Measured:
3. Take the reading of all the ammeters for KCL
experiment and measure the voltages across all
the resistors for KVL experiment.
2) KCL:
Measured: SR No
- (^) Changed the (^) voltage of (^) power supply and
