How Electricity Works
Ken Brewer
MCOMM 520

Electric sources
• Generator – Converts
mechanical energy
into electrical engergy
• Battery –
Chemical Energy
Generates Electricity

Stepping Down
• Power Station – Sub Station – Step Down
Transformer – Service Panel

Using Electricity
• Service Panel to 120V outlets in your home

Electronics
• DC Power Supply
converts 120VAC
to DC
• Electronics = less
than 1 amp (1 amp
can kill you)

Ohm’s Law
• V = I x R
• R = V/I
• I = V/R

Ohm’s Law
• V = I x R
• R = V/I
• I = V/R
