The document summarizes an experiment to verify the laws of series and parallel resistor combinations using two carbon resistors, a circuit board, wires, a 9V battery, and a multimeter. It confirms that the laws of series and parallel resistor combinations hold true. Applications include inverters, voltage stabilizers, and battery eliminators used in many electronic devices. Precautions include connecting components in series to prevent burning from excessive current.

1. Aim
To check the laws of series and paralle combinations using two different carbon
resistors and multimetre.

2. Introduction
Define laws of series and parallel combination of resistors.

3. Apparatus used
Circuit board
Wires
9V battery and battery connector
Multimeter
Resistors

4. Theory and working

7. Conclusion
The law of series and parallel combination are verified.
Sources of errors

Precautions
Do not connect any electronic component without resistance in series, it can
burn the component.
Applications
In inverters, voltage stabilizers, battery eliminators and almost all electronic
devices.
