How do you test a diode

Why do we connect a resistor to a battery source in a circuit? In simple to current limit, to decrease current, to regulate voltage. Resistors are not added to the circuit randomly. A designer has

All FETs can be called UNIPOLAR devices, because charging carriers carrying the current through the device are all of the same type, that is, either holes or electrons, but not both. This distinguishe

The fan has an AC motor. Now, when a capacitor is added to the additional auxiliary winding of the stator, a field is created which goes 90 degrees to the main winding field, so we get two fields that
