Pak Elektron Ltd (PEL) was founded in 1956 through a technical collaboration with AEG.In 1978, PEL was acquired by Saigol Group and was taken public a decade later. In 2009, PEL became the sole distributor of LG Corporation's home appliances in Pakistan.
In North America and northern South America, it is usually 120 volts, 60 hertz (Hz), but in Europe, Asia, Africa, and many other parts of the world, it is usually 230 volts, 50 Hz. [2] Aircraft often use 400 Hz power internally, so 50 Hz or 60 Hz to 400 Hz frequency conversion is needed for use in the ground power unit used to power the ...
On May 2, 2002, Panasonic Canada marked its 35th anniversary in that country by giving $5 million to help build a "music city" on Toronto's waterfront. [45] In 2005, Matsushita Toshiba Picture Display Co. Ltd. (a joint venture between Matsushita and Toshiba created in 2002 [46]) stopped production of CRTs at its factory in Horseheads, New York ...
When the RMS voltage exceeds the nominal voltage by 10 to 80% for 0.5 cycle to 1 minute, the event is called a "swell". A "dip" (in British English) or a "sag" (in American English – the two terms are equivalent) is the opposite situation: the RMS voltage is below the nominal voltage by 10 to 90% for 0.5 cycle to 1 minute.

The U.S. National Retail Federation, which is chaired by Walmart's top U.S. executive, John Furner, said in October that holiday spending in the last two months of the year was expected to grow by ...
In a simple alternating current (AC) circuit consisting of a source and a linear time-invariant load, both the current and voltage are sinusoidal at the same frequency. [3] If the load is purely resistive, the two quantities reverse their polarity at the same time. Hence, the instantaneous power, given by the product of voltage and current, is ...
