Lesson goals:
  • Explain how electricity is generated.
  • Explain how a dynamo works.
  • Explain what is meant with induced- and alternating current.
  • Use the formulas
                                               and

                to calculate the unknown values.
P=UI
E=Pt

Nuclear power
Enegry is generated by splitting the nuclei of atoms.

Slide 5 - Link

Dynamo

Slide 6 - Slide

Induction
If the magnetic field changes in a coil, 
there is a potential difference on the ends of the 
coil. This is called induction.

The generated potential difference
is called induced current.

Slide 7 - Slide

Alternating current

Slide 8 - Slide

Power



U is potential difference in (V)
I is current in (A)
P is power in watt (W)
P=UI

Slide 9 - Slide

Electrical energy



P is power in watt (W)
t is time in seconds (s)
E is Energy in joule (J)
E=Pt

Slide 10 - Slide
