DC Circuits and Ohm’s Law


To learn the basic concepts of Direct Current (DC) electric circuits by measuring voltages and currents in some simple circuits.

Equipment List:

  • Component Board F1
  • Pasco 550 interface F5
  • Pasco 550 power supply F5
  • DMM (any type) to measure ohms F4
  • Leads:
  • 1 pair B/B medium
  • 2 pairs B/B stack short

Setup: Setup components like displayed in the image


concept: Ohm’s Law, V= IR is a critical component of understanding the basis of E&M. Observing changes in voltage and current through the use of resistors and capacitors helps demonstrate the properties of Ohm’s law.
