Series & Parallel Circuits (152)
BlackBoard Notes

======================= Photo - Click for a Larger Version =============================

================== First Board Section – Note: use R_set below, not R_eq! ========================

• For each resistor circuit examined:
  • What is the relationship between:
    • …the measured voltages?
    • …the measured currents?
  • What is the equivalent resistance of the pair, R_set?

======================= Second Board Section =============================

Resistors in series:

If we had a lot of meters… (write this between the two diagrams with meters)

======================= Third Board Section =============================

Resistors in parallel:

======================= Fourth Board Section =============================

• Short circuit:
  • No meters needed!
    • Short circuit – bulbs in series:
      • Have your circuit checked before proceeding!
    • Short circuit – bulbs in parallel:
      • UNPLUG POWER SUPPLY BEFORE CONNECTING!
      • Why do I ask you to do this?
