The Poynting theorem is one of the most important in EM theory It tells us the power flowing in an electromagnetic field John Henry Poynting (1852-1914) John Henry Poynting was an English physicist He was a professor of physics at Mason Science College (now the University of Birmingham) from 1880 until his death

What is the Poynting factor?

At system pressures up to several tens of MPa, the fugacity coefficients, ( ) and and the Poynting factor, 7T, are usually near unity. A simplified version of equation 19 can therefore be used for the majority of vapor—Hquid equihbrium problems ... [Pg.235] The exponential is known as the Poynting factor. Equation (4-277) may now be written...

What is power factor correction and why is it important?

Power factor correction is a key issue for the UK industry that impacts on energy efficiency and electricity bills. On top of this, the reliability and availability of the equipment and network infrastructure is just as important. Variation in the power factor readings or a poor rating is caused by different types of electrical devices.
