1 An Introduction to Amateur Radio

2 The purpose of Amateur Radio “To encourage self- training in radio”

3 Education vs Training STELAR: Education

4 Foundation Licence Technical Basics The BIG 3

5 The Big 3 Current (Amps) Resistance and Impedance (Ohms) Potential Difference (Volts)

6 A peculiar way of thinking? Current as electron vibration

7 A peculiar way of thinking? Resistance: transfer of electron energy to atoms resulting in energy dissipation by heating.

8 A peculiar way of thinking? Electrical Potential = energy possessed by electrons Potential Difference = energy transferred from electrons to a component

9 V = IR

10 Battery / Cell provides Potential Difference for circuit Battery/Cell source of Direct Current (DC).

11 Frequency
