Daya dan energi listrik ppt

  1. 1. Electrical power is electrical energy that is produced or needed per time unit.
  2. 2. P = W / TP = Power (Watt)W = Energy (Joule)T = time unit (Second)
  3. 3. P = W/T W = V.I.T = V.I.T V = I.R = V.I I = V/R = I2 . R = V2/ R
  4. 4. Energy is all power that is produced in unit time. In international system, the energy unit is Joule. In daily life, the electrical energy unit is kwh (kilowatt hour) 1 kwh = 3,6 x 106 joule
