• Current (Amps)

• Resistance and Impedance (Ohms)

• Potential Difference (Volts)

Page 6: An Introduction to Amateur Radio. The purpose of Amateur Radio “To encourage self- training in radio”

A peculiar way of thinking?

Current as electron vibration

Page 7: An Introduction to Amateur Radio. The purpose of Amateur Radio “To encourage self- training in radio”

A peculiar way of thinking?

Resistance: transfer of electron energy to atoms resulting in energy dissipation by heating.

Page 8: An Introduction to Amateur Radio. The purpose of Amateur Radio “To encourage self- training in radio”

A peculiar way of thinking?

Electrical Potential = energy possessed by electrons

Potential Difference = energy transferred from electrons to a

component
