Avocados are high in fat. But it's monounsaturated fat, which is a good fat that helps lower bad cholesterol, as long as you eat them in moderation. Avocados have a lot of calories. The recommended serving size is smaller than youâd expect: 1/5 of a medium avocado (or 1 ounce) is 50 calories.
Why do transformers hum? Transformer noise is caused by a phenomenon which causes a piece of magnetic sheet steel to extend itself when magnetized. When the magnetization is taken away, it goes back to its original condition. This phenomenon is scientifically referred to as magnetostriction.
No slip rings or brushes are required since the. load currents in the rotor conductors are induced by transformer action. The induction motor is, in effect, a transformer - with the stator winding. being the primary winding and the rotor bars and end rings being the. movable secondary members. Both single-phase and polyphase (three-phase) AC motors are produced by. LEESON and many other manufacturers.
