History behind Ohm Cont. What did people think of Ohm’s law?

Coldly receivedLater 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:

CurrentResistanceVoltage

Conclusion I = V/R Basic algebra skills are needed Ohm’s law is a must in electronics It is easily proved
