Thus, if in the original stream isotopes of various masses are present, the position of the blackened spots on the plate makes possible a calculation of the isotope masses.
Almost all electrical appliances come for a standard voltage. Depending where you live, this is usually about 110 volts in some areas, and about 220 volts in other areas. You can take a look at a specific appliance; there is usually a metallic sticker that has the electrical specifications.
Answer Wiki. A typical home microwave transformer has two secondary windings. One winding provides 3.1 to 3.2 volts, while the high voltage winding provides between 1800 - 2800 volts (average ~2200 volts). The low voltage output is used to light the filament in the microwave-generating vacuum tube (called a magnetron).
