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).
Snuff is a smokeless tobacco made from ground or pulverised tobacco leaves. It is insufflated or snuffed into the nasal cavity, delivering a swift hit of nicotine and a lasting flavoured scent (especially if flavouring has been blended with the tobacco).raditionally it is sniffed or inhaled lightly after a pinch of snuff is placed onto the back surface of the hand, held pinched between thumb and index finger, or held by a specially made snuffing device. It originated in the Americas and was in common use in Europe by the 17th century.
