Learn MoreTo solve the problem of sending electricity over long distances, William Stanley developed a device called a transformer. A transformer changes the voltage of electricity in a conductor or power line. High-voltage transmission lines, such as those that hang between tall metal towers, carry electricity over long distances to where it is needed.
Learn MoreTransformer copper losses come from the ohmic resistance in the windings. These losses affect how well the transformer works. They change with the current load, increasing as we use more energy. Copper losses are known as I2R losses. ''I'' stands for the current in the windings, and ''R'' is the copper''s resistance.

Learn MoreWhy do so many sources say something along the lines "since a flyback transformer stores energy, an air gap is needed"? I have seen this reasoning in textbooks and app notes. I thought air gaps cannot store energy and I thought also a flyback transformer stores energy with its inductance, and an air gap reduces inductance so I would think it also …

Learn MoreTransformers are manufactured to be step up or step down transformers and these are used to increase or decrease the voltage simply by using a different number of turns within the coil on the secondary side. In a step up transformer, the voltage is increased in the secondary coil and this will mean that the current will …
Learn MoreOr, it can move through a turbine to generate electricity. When it comes to circuits and electronic devices, energy is typically stored in one of two places. The first, a battery, stores energy in chemicals. Capacitors are a less common (and probably less familiar) alternative. They store energy in an electric field.

Learn MoreThe magnetic field which stores the energy is a function of the current through the inductor: no current, no field, no energy. You''ll need an active circuit to keep that current flowing, once you cut the current the inductor will release the magnetic field''s energy also as a current, and the inductor becomes a current source (whereas its dual, …
Learn MoreWhen combined with Equation 12.6.1, this gives. (12.6.3) If the voltage is stepped up, the current is stepped down, and vice versa. Finally, we can use along with Equation 12.6.1 and Equation 12.6.3, to obtain. which tells us that the input voltage "sees" not a resistance but rather a resistance.

Learn MoreWhen ATP is broken down, usually by the removal of its terminal phosphate group, energy is released. The energy is used to do work by the cell, usually by the released phosphate binding to another molecule, activating it. For example, in the mechanical work of muscle contraction, ATP supplies the energy to move the contractile muscle proteins.
Learn MoreNo, a 220v transformer cannot store electric charge indefinitely. The stored charge will eventually dissipate due to internal resistance and leakage in the transformer. The duration of time that the charge can be stored will depend on the quality and design of the transformer.
