Hamilton’s principle states that the motion of a system is such that the action functional S q(t) = Zt2 t1 dtL(q,q,t˙ ) (6.2) is an extremum, i.e. δS = 0.

courses.physics.ucsd.eduPower Transmission Transmitting electrical power is done much more efficiently at higher voltages due to the desire to minimize (I2R) losses. Consider power transmission to a small community which is 100 mi from the power plant and which consumes power at a rate of 10 MW. In other words, the generating station needs to supply whatever power it ...
