qestion 1 is what is the component of electrical machine 2 what is transformer.?
Typical components of electrical machines include power source(s), resistors, inductors, capacitors, diodes, and transistorsA transformer, usually changes the voltage by stepping it up or downA step up transformer increases the voltageIf it's AC (alternating current) it may increase it from 110V to 220VIf DC (direct current) it may increase it from 5 V to 12V or many other possibilitiesA step down transformer does just the oppositeBy increasing the voltage, a transformer decreases the current (I)V IRVoltage current times resistanceBridge circuits are used to convert AC to DCFurthermore a transformer is usually a coil of wires that create an electric field, thus changing the voltage from one side of the transformer coil to the otherThe number of wire coils relates to the electric field and therefore the potential voltage and current changeThere's a lot more to it, but this includes some of the basics.
