Nyric Timmons Lab Report 2 Ohm’s Law and Introduction to Circuit Simulation

Project Title : Ohm’s Law and Introduction to Circuit Simulation Objectives : The overall purpose of this lab was to get a better understanding of Ohm’s Law. We applied equations to values we collected during the lab in order to better understand what goes on in the context of circuitry as well as what goes on in the circuit simulations that occur in LTSpice. We first were asked to calculate resistance values, based on DC power values that we manually did. Another method of measuring resistance could have been to collect the values from the resistance box, but to better understand Ohm’s Law we performed calculations by hand. Equipment : ● 5 Banana Plug Wires ● Voltmeter ● Ammeter ● LTSpic on Laptop ● DC Power Source ● Resistance Box Procedure: 1. Wire Circuit according to the circuit diagram that can be found in the lab handout. 2. Turn on the Equipment 3. Record the current and voltage and 5 different DC power source voltage inputs that varies group to group 4. You adjust the input by SLOWLY turning the knob (make sure you stay within the range of 1-5 Volts) 5. Read and record the current and voltage values that are located on the voltmeter and ammeter 6. Use LTSpice and create a simulation of the circuit Observation and Discussion : So Equation (1) delineates ohm's law, using the formula V=I*R, keeping in mind that V symbolizes volts, I symbolizes Current in amperes and R representing resistance in ohms. The mean resistance value derived from the table that we were asked to fill out Was 2.0123 ohms. The data from that table was put into a graph showing the relationship between voltage and current, and those values were Plugged into equation (2). The graph has a slope of approximately 0.499. When you use equation (2) and plug in the values to gauge Resistance from the graph yields a result of 2 Ohms, which is almost exactly the same as the average resistance calculated from the values in Table 1. The procedure used allowed us to successfully accomplish the overall goal of understand how ohms law works, while imputing Different values for the DC power supply. The LTSpice program we used for the simulation of circuits helped me to better understand the Fundamental principles of circuitry when in series. The outputs from the simulation confirmed that current tends to remain somewhat uniform Throughout a series circuit loop, voltage can vary. A potential source of error could root from unstable equipment, leading to Measurements that are not quite accurate. Conclusions : The lab that we conducted this week introduced the practical implications of Ohm’s Law. We used a physical wired circuit to gather The data that came from the ammeter and voltmeter. The information we gathered was used to determine the resistance in the circuit using The hands-on aspect in the lab. The outcomes of the LTSpice further helps me understand Ohm’s Law and illuminated the behavior Of current and voltage within series connections. In order to enhance the overall lab experience and learning could be enhancing by making sure all the equipment works properly prior to performing the experiment. I also think that offering more hands on help with using the LTSpice program Would help improve lab results
