Two experiments related to electrical circuits and measurement techniques. The first experiment focuses on dc measurement techniques, including the proper use of voltmeters and ammeters, as well as the importance of correctly connecting circuits to power supplies. The second experiment explores ohm's law, demonstrating the relationship between voltage, current, and resistance, and the calculation of power dissipation. Detailed information on the apparatus, procedures, data collection, and safety precautions for both experiments. It aims to enhance the understanding of fundamental electrical principles and their practical applications in the field of electronics.

In the realm of electronics system design, it is imperative to possess a profound comprehension of voltage, electric current, and the precise methods for their measurement. This necessitates proficiency in interpreting meters and grasping the distinctive traits of measurement instruments to avert inaccuracies and potential harm to equipment. When assessing the current flowing through a load, it is customary to employ an ammeter connected in series, while a voltmeter, connected in parallel, gauges the voltage across the load. A meticulous grasp of these principles is of paramount significance in the field of electronics to ensure their accurate application. Current and voltage assume pivotal roles, particularly in the context of energizing electronic devices through a power supply. In the case of a direct current (DC) power supply, there exist two polarities – positive and negative. It is imperative to correctly connect the circuit to the appropriate polarity of the power supply to guarantee its proper and secure operation.

For the third part of the experiment: No. Polarity I/ A VR / V 1 Positive 0.09 4 0.30 2 2 Positive 0.09 7 0.3 18
This experiment enhances our comprehension of the flow of electric current within a circuit. It elucidates that within a voltage source, current moves from the negative to the positive polarity, whereas in a load, it travels from the positive to the negative polarity. Additionally, we gained insights into the correct connection of voltmeters and ammeters within a circuit to guarantee accurate readings.
The gathered data confirms the validity of Ohm's law, demonstrating that the voltage across a load is in direct proportion to the current, assuming a constant temperature. Additionally, the power dissipated across the resistance remains consistent when utilizing the provided formulas. In summary, this experiment aids in comprehending Ohm's law and its practical applications.
