For this project, a simple circuit was created in TinkerCAD and LTSpice to show how a voltage divider works. Using a series of resistors, the output voltage will be a fraction of the input voltage, which is determined by the size of the resistors. We can confirm this is exercising how to Ohm's law works.Ohm's Law is Voltage = Current X Resistance. By manipulating the equation, we can prove that the Vout is direction proportional to Vin. the Equation used is :

df = pd.read_csv("TinkerCAD.csv") Vps = df.Vps Vpr = df.Vpr R = 1000 I = (Vps - Vpr)/R m, b = np.polyfit(I, Vpr, 1) Vth = m*I + b plt.title("TinkerCAD data") plt.ylabel("Voltage") plt.xlabel("Current(mA)") plt.plot(I, Vpr, 'b.', label='data') plt.plot(I, Vth, 'r-', label='fit') plt.legend()

lt = pd.read_csv("LtSpice.csv") Vps2 = lt.v1 Vpr2 = lt.V2 R = 1000 I = (Vps2 - Vpr2)/R m, b = np.polyfit(I, Vpr2, 1) Vth = m*I + b plt.title("LTSpice data") plt.ylabel("Voltage") plt.xlabel("Current(mA)") plt.plot(I, Vpr2, 'b.', label='data') plt.plot(I, Vth, 'r-', label='fit') plt.legend() m, b = np.polyfit(I, Vpr2, 1)
