aSave electricity. It is crucial. We can't imagine what the life will be like without it.Everyone should do his best to save electricity. Don't forget to turn off lights or other electric machines when we finish working Save electricity. 它是关键的。 我们不可能想象什么生活将是象没有。大...
The power factor, often abbreviated to PF is a basic concept for electrical systems of all types. Although power factor is not often mentioned in many arenas it can be a concept that is of considerable importance in many areas of electrical and electronic engineering. What is power factor In ...
In simple words, we can say that a capacitor is a device used to store and release electricity, usually as the result of a chemical action. Also referred to as a storage cell, a secondary cell, a condenser or an accumulator. A Leyden Jar was an early example of a capacitor....
Static electricity is usually artificially generated, and during processes such as production, assembly, testing, storage, and handling, static electricity may accumulate in the human body, instruments, or equipment. Even electronic components themselves may accumulate static electricity. When people unknowi...

and the properties of the dielectric material between the conductive plates. The unit of capacitance is the farad and can be measured in farads, which is the unit of capacitance. Capacitors are often rated in microfarads (μF) or picofarads (pF), depending on their size and intended use....
❷ With its capacitance ranging from 8 pF to 250 pF, the chip varistor operates effectively at low to high communication speeds.Summary In an EV, many in-vehicle equipment (except the motor) operates at a voltage far lower than the source voltage of the EV. The DC/DC converter is there...
Once Green Electricity Certificates have been sold, a power producerloses the right to receive a subsidyfor electricity based on the corresponding amount pf Green Electricity Certificates sold. ( It can only receive subsidies or sell Green Electricity Certificates.) ...
Firstly, the current waveform is in phase with the voltage, and secondly both waveforms are sinusoidal. Fig 1: Input voltage and current waveforms for a device with PF = 1.0 In practice, some devices do have unity power factors, but many others do not. A device has a poor p...
