Thomas A. Edison Papers. Electric Generator. In the fall of 1878, after experiments indicated that existing arc light generators were inefficient for incandescent lighting Edison and his chief assistants, Charles Batchelor and Francis Upton, investigated generator design and the principles of electromagnetism.
Stove/Oven Height. When it comes to height, there are some variations. Average heights for a stove/oven combo are either 37.25 inches or 47 inches, depending on the manufacturer. The most common height of 36 inches accommodate standard counter heights.
1kw or 1000 watts is normal The above figure is not typical. An average two slice toaster will use 1000 watts. An electric oven, at least in North America, will usually be clo â¦ ser to 4000 watts. The ones I have looked at vary from a low of 3000 to upwards of 9000 watts for prosumer appliances. Each oven has a label on the inside door panel. The label shows how many total watts (W) or kilowatts (KW). For example a Gibson 240 Volt upper & lower combination oven uses 7.4 KW or 7400 watts. The watt rating assumes both upper and lower ovens can be turned 'on' at same time.
