reactive power losses

This disease is characterised by bleeding gums, loosening of teeth, muscular and joint pain, along with general weakness, fatigue, loss of weight and poor healing power..

Electric power is usually generated at places which are far from the places where it is consumed. Distribution of Electricity from Grid The power is transmitted over long distances at high voltage to minimize the loss of energy during transmission. For a given electric..

If the two bodies stick together after the collision, the collision is said to be perfectly inelastic. In this type of collision, the loss of kinetic energy is maximum but not complet..

where W 1 is the input power and W 2 the output power. If W W 2 exceeds W 1 , the value is positive and is spoken of as again. When W 1 exceeds W 2 the expression will be negative and indicates a loss. The decibel is also used as a measure of the amount of power..

To prevent the losses of heat and to protect the persons operating the reactor from the radiation and heat, the entire reactor core is enclosed in a heavy steel or concrete some called the shield. In nuclear power plants, the large amount of energy which is released in the form..

Atomic Hydrogen - Langmuir ,in 1915, obtained atomic hydrogen by dissociating on a hot filament of tungsten or platinum. The dissociation of molecular hydrogen is an endothermic process. The atomic hydrogen is stable only for a fraction of a second and immediately reverts back to its molecular form..

. A choke coil is basically a coil of high inductance L and a small resistance r connected in series. The Average power consumed over a complete cycle in a practical choke coil is P = E r m s I r m s cos..

Maximum EMF E 0 = NBA w = 20 x 3 x 10 - 2 x 3.14 x (8 x 10 - 2 ) 2 x 50 volt = 0.6 volt Average EMF for one cycle is zero. Maximum current, Power loss The source of this power is the external agent (motor) which helps the coil rotating against the torque of ..

Practical Applications of Joule's Heating - This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe it. Often, this is an undesirable effect. For example, in elec..

. The major problem of corrosion occurs with iron (or steel) as it is used as a structural material in industries like construction, infrastructure, bridges, rail transport power transmission, shipbuilding, automobiles, heavy industries etc. Aluminium, another useful structural metal, als..
