Power Power • P = work/time (J/s) or (Watt) • P = I* V • The “Power” company charges you by the Kilowatt Hour or Kwhr. What unit are they really charging? If you left a 60Watt light bulb on continuously for 30 days how much would it cost you? What would happen if you plugged a 30watt light bulb from your car (12V) into a socket in your house (120V)? Questions • Why are Christmas lights wired is series? • If high voltage is dangerous why does the power company transport electricity at such high voltages? • Why is your car 12V and your house 120V? • Is your house wired in series or in parallel? Why? • Why is it bad to rate light bulbs by Watts?
