History Behind Ohm
Georg Ohm: March 16, 1789 - July 6,
1854
 Taught Math at Jesuits' College in
Cologne (1817 – 27)

History behind Ohm Cont.

What did people think of Ohm’s law?
 Coldly received
 Later became widely recognized
….And yes the measurement of Ohm was
named after Georg Ohm
Required Equipment





Multimeter
DC power supply
Resistors
Vulcan trainer board
Laptop with excel installed and/or
Calculator
Ohm’s Law
I = V/R
 E and V both mean
voltage
 Simple algebra skills are
required
 Is the foundation in circuit
analysis

Ohm’s Law Demonstration

We will now demonstrate how we use
Ohm’s law in the field of electronics.
Demonstration Conclusion

We predicted and proved using Ohm’s Law:
 Current
 Resistance
 Voltage
Conclusion
I = V/R
 Basic algebra skills are needed
 Ohm’s law is a must in electronics
 It is easily proved
