Circuit Lab Report EssayOhms practice of law is V = I * R or in some cases I = V / R. The next twain laws were establi fuddle by a German physicist by the name of Gustav Kirchhoff. Kirchhoffs first law is his potency law. Kirchhoffs Voltage fairness (KVL) states that around any loop in a round, the voltage rises essential equal the voltage drops. The next law that Kirchhoff introduced was his accepted law. Kirchhoffs Current Law (KCL) states that the total online entering a junction must equal the total current leaving the junction. These laws, however, cannot be prove or tested without the aid of a mul cartridge holderter. A mul erater is an instrument designed to measure electric current, voltage, and commonly resistance, typically over several ranges of value. The multimeter has different programs to measure voltage, current, resistance, etc. produced from one of two pillowcases of circuits.The first type of circuit is a series circuit. A series circuit is a circ uit in which the components atomic number 18 arranged end to end in such a way that the electric current flows with the first component, through the next component, and so on, until it reaches the source again. In contrast, a parallel circuit is a circuit in which the has more than one resistor and has multiple paths to move along. The main purpose of this research laboratory was to prove the laws of Ohm and Kirchhoff. On another note, being able to take part in this lab taught my associate and I the fundamental skills of constructing series and parallel circuit and using a multimeter to calculate the current and voltage of a circuit.I believe that if we only have the basic materials to conduct electricity (such as resistors, crack clip, cords, a multimeter, and a fountain source), then we can still prove the that the laws that Ohm and Kirchhoff established are in fact reliable sources for calculating data regarding certain electrical circuits. Ive reached this hypothesis becau se Ohms laws and Kirchhoffs two laws are supposed to be laws used for any electrical circuits. Based on this, these terce laws should be able to be validated with this experiment.Materials Power Source Alligator Clips 1,000 Ohms Resistor 10,000 Ohms Resistor MultimeterMethodsOhms Law1.

We took our time and did not rush through this lab, so we could get the best results, but we did have some affect with our Multimeter on more than one occasion. For example, while we were attempting to prove Ohms Law and Kirchhoffs Voltage Law. The Multimeter, at first was acting up and completely just not working, but we then realized that it was not set on the correct measuring task. Then, on the same two labs, we were getting readings from the Multimeter that made no sense. It told us that the current for the circuit was 967.83 Ohms which for the type of circuit that we built, was impossible.After fixing the problem with the Multimeter and proving Ohms Law and Kirchhoffs Voltage Law, we moved onto the Current Law that Kirchhoff established. This time, the problem wasnt the Multimeter, or the resistors, or the power supply, or anything else. It was us. We were overall a bit confused on how th e circuit was created and it took a long time to horizontaltually construct and then prove. Even though the problems were an annoyance, the lab was very insightful and taught us a lot about electric currents and circuits.ConclusionAt the conclusion of this experiment, our results supported our hypothesis greatly even though our numbers were not a hundred percent on point. But there is direction for faulting, like the fact that the power supply was not great quality and doesnt give scarce 3 volts or 4.5 volts or any of that. Also, the resistors are not high-quality resistors and are also worn have from years of use, so they dont give exactly 1,000 / 10,000 Ohms like we were looking for. Other sources of error included the Multimeter, which was not exact because the Multimeter rounds numbers, the Alligator clips, which are (like the power supply and resistors) not the best and shed energy, and our calculations, which could have suffered from any addition or multiplication or divi sion error.
