Electric Current: Currents, Resistance, and Power

lab Lab: DC Circuits

In this lab you will create various electrical circuits using the simulation. Take measurements of current and voltage drops across resistors in your circuits. Your mission is to use the simulation to determine the relationship between current through a resistor and the voltage across the resistor.

Your write-up should include:

  • Objective: What was being investigated? What were you trying to find?
  • Theory: What’s going on? Include here the equations you will be using and any needed manipulations of them. They should be clearly explained, with connections to physical laws and diagrams where appropriate.
  • Method: Description of the procedure you used, including materials and diagrams where necessary.
  • Data: Observations from doing the experiment; graph(s) of data.
  • Analysis: Analyze data. Final experimentally determined equation.
  • Discussion: Discuss the experiment. Draw conclusions from data; suggest ways to improve the experiment and/or further investigations.
