Prime purpose of this lecture is to present on Using Electricity in Home. Here briefly describe on about House Hold Energy Consumption. Hydro bills are established by finding out how many kilowatt hours of electricity your household has used in a given time. 1 kWh = kilowatts X time (hours); 1 kWh = 1 000 Watts X 1 hour and 1 kWh = 1 000 W X 3 600 seconds. Here also describe on House Hold Wiring. The wires coming into a house include a black, a red and a white. The black and the red wires are “hot”. The white wire is neutral – leading to a ground.
