By Matt Rosenberg. A nations economy can be divided into various sectors to define the proportion of the population engaged in the activity sector. This categorization is seen as a continuum of distance from the natural environment.he packaging and processing of the raw material associated with this sector is also considered to be part of this sector. In developed and developing countries, a decreasing proportion of workers are involved in the primary sector.
RC SNUBBERS (SMPS) Snubbers are energy-absorbing circuits used to suppress the voltage spikes caused by the circuit's. inductance when a switch, electrical or mechanical, opens. The most common snubber circuit is a. capacitor and resistor connected in series across the switch (transistor).
When the circuit is switched off, a capacitor retains the energy it has gathered, though slight leakage usually occurs. A variety of capacitors (shown in color) in circuit board. Capacitance is expressed as the ratio of the electric charge on each conductor to the potential difference (i.e., voltage) between them. The capacitance value of a capacitor is measured in farads (F), units named for English physicist Michael Faraday (1791â1867). A farad is a large quantity of capacitance. Most household electrical devices include capacitors that produce only a fraction of a farad, often a thousandth of a farad (or microfarad, ÂµF) or as small as a picofarad (a trillionth, pF).
