For example, if a battery that drives a device generates 9 volts, it produces a difference of 9 volts at its two terminals. That is, if you measure the voltage at…

Motor protection is the isolation of the motor from the main supply in the event of an abnormal condition in the operating state of an motor (i.e. when the motor…

Earthing provides a low impedance ground path for power if an insult fails and a live cable comes into contact with an exposed part of a device, causing the device…

There are basically two principles that govern a DC motor. How to repel poles of a magnet and tighten them differently. We have all played with magnets and are familiar with…

There is always a tendency to choose a higher frequency to reduce the size of the inductor and capacitor to minimize the size of the converter. However, it does not necessarily…

VDC is an abbreviation for “Volt DC”. DC stands for “direct current”, which means that the voltage is constant (in contrast to alternating current, alternating current, in which the voltage oscillates…

The current consumed by the LEDs is given by (Vin-Vf) / Rs which depends on the applied input voltage Vin, the direct voltage drop of the LEDs Vf and the…

Methods of electricity generation There are seven basic methods to convert other forms of energy directly into electrical energy: Static electricity through physical separation and charge transport (examples: triboelectric effect…

There are mutliple reasons for this: Tube amplifiers produce more even harmonics than solid state amplifiers. Solid state amplifiers, on the other hand, are rich in odd order harmonics. For some evolutionary…

A  rectifier  is an electrical device that consists of one or more diodes and converts alternating current (AC) to direct current (DC). A diode is like a one-way valve, in which electrical…
