DC Circuits

Description: In this lab, students will be working with circuits to gain a familiarity with Ohm’s law and learn how to manipulate galvanometers as voltmeters and ammeters.


  • Per Station (12 stations):
  • Pasco 550 interface F5
  • Pasco 550 power supply / cables F5
  • Voltage Probe lead F1
  • Component Board F4
  • Leads: 218
  • 2x Medium
  • 4x Short



This experiment mostly uses the resistors. Can be wired to bypass switch and

potentiometer. Also uses the small glow bulbs. Extra bulbs are in the component board

“parts box.” Voltage from 550 should be set to 3vdc. Use template “DC circuit.”
