4. Current
• An electric current is a flow of electrons moving through a
connector

5. Voltage.

6. Types of Electricity
• Static electricity results from an imbalance between
negative and positive charges in objects.

7. Types of Electricity
• Dynamic electricity is the flow of electric charges through
a conductor; in other words, an electric current.

8. •DC•AC

11. AC
• Period.
• Frequency.
• Amplitude(Vp).
• Vrms.
• Phase Angle.

15. Ohm’s law.
• The current in a circuit is directly
propotional to voltage and
inversely propotional to resistance.
