# Project 0: Characterizing an Unknown Component Manually

## Abstract:

For this project students were tasked with using two different programs, TinkerCAD and LTSpice, to create two different simulations of a voltage divider. Once they created these simulations they were tasked with collecting data from them and using this data to create two different graphs.

## Description:

In this weeks project students had to create two different simulations of voltage dividers on two different programs, TinkerCAD and LTSpice. For this project students were tasked with using two different programs, TinkerCAD and LTSpice, to create two different simulations of a voltage divider. The purpose of this project wasn to get comfortable with Deepnote, learn about simulators that will be used in the course, get data into Deepnote, and write a simple report about the project. A voltage divider working by taking the input voltage and producing an output voltage a fraction of it's input voltage by distributing the voltage among the components of the divider. In TinkerCad they had to create a circuit that minics a voltage divider circuit by taking a power supply, resistor, and a photo resistor in series. Then attaching a multimeter to the circuit to measure the voltage drop. From there manually creating data from the circuit. Data such as the input voltage from power supply and output voltage caused by the circuit. The data was recorded by changing the input voltage from a range of 1 - 10 volts taking the voltage drop displayed on the mutlimeter at increments of 1V of the range.

In LTSpice the students had to create a circuit consisting of a power supply and two resistors connected in series. Running the simulation and collecting data automatically through the program. The data collected was input voltage and output voltage caused by each resistor in the same increments of 1 Volt from range 1 volt - 10 volts from the power supply.

They then took this data and used it to create two different graphs. These graphs showed the calculated current on the X axis and voltage of the power supply on the Y axis with the slope of each of the graphs being the resistance of the first resistor. To calculate the current the equation used was:

$ I = \frac{Vps - Vpr}{R} $

After this was plotted on the graphs the line best fit was also created and added to the graph.
