Ohm's Law - 104
BlackBoard Notes

• Note to Jeff: Power on all meters to check battery; set all for h_FE before each lab section!

======================= First Board Section =============================

• Circuit elements: Resistor, bulb, LED. Which follow Ohm's Law? (ohmic)
• Follow the directions carefully; add meters only when instructed!
• Always connect voltmeter last!
• Record all meter settings!

• Ammeter Setting:	Units Displayed:
  2 DCA	amperes (A)
  2m DCA	milliamperes (mA)

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

Ohm's Law: V = IR (Insert Graph Here!) Why is R = 1/slope? y = (slope)x + b I = (1/R)V Don't convert units!

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

• The circuit: Only Draw Circuit Diagrams!

  Without meters:		With meters:
  	Ugh!! ☹

• Circuit diagram:

  Ahh!! 🙂

• Draw circuit diagrams on paper when the circuit changes. Use a ruler!
• Add diagram to journal and hand in

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

• Draw circuit elements carefully:
  • 
• Don't get lazy!
  •
