Resistance (R) in a circuit is equal to the voltage (V) divided by the current (I) and is expressed as R = V/I, provides the theoretical foundation for this experiment. The goal is to understand how resistors—in this case, light bulbs—behave in series and parallel configurations. In a series circuit, resistances add together to produce a higher total resistance. In contrast, in a parallel circuit, the reciprocal relationship between individual and total resistances causes the total resistance to decrease. The DMM is used to measure resistance, current, and potential difference. It functions as an ammeter, voltmeter, and ohmmeter. Through the analysis of these configurations and the application of the DMM, participants will gain a deeper understanding of the basic concepts underlying electrical circuits.
