Ohm's Law
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 to circuit 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 Keep units in A or mA as measured. Don't convert!!

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

• The circuit: Don't draw sketches, on circuit diagrams!

  Without meters:		With meters:
  	Ugh!!

• Circuit diagram:

  Ahh!!

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

• Correct way to draw circuit elements, e.g. resistors:
  • 
• Fail the exam!
  • 
• The same goes for drawing all circuit elements!
