Equation is satisfied when=. The maximum power is=

Let us first define a linear element as passive element that has a linear voltage-current relationship

We select one node as a reference node and then define a voltage between each remaining node and the reference node

The ideal voltage source and a series resistance comprise a practical voltage source

The series combination of voltage sources: Several voltage sources in series may be replaced by an equivalent voltage source having a voltage equal to the algebraic sum of the individual sources

Ohm's law states that voltage across many types of conducting materials is directly proportional to the current flowing through the material. U= Ri or R= i R--resis tance()( linear resistor) The resistor is a passive element that cannot deliver power or store energy

理论上,偶合器工作时,工作液的体积等于偶合 器内部工作腔的体积时,应该是完全充满的。在实际工作中,工作液体积只占内部工作腔的90%左右就算完全充满。留下部分空间来容纳从工作液中分解出来的空气和油气
