The Earth consists of deformable matter capable of responding to internal and
external applied forces . The forces generate internal stresses that are
accompanied by deformation , or strain . Stress may be defined as the force per
unit area ...
Electromotive force and internal resistance . All practical generators of
electromotive force involve real conductors of nonzero resistance . For example ,
in a battery the resistance to the flow of electric current is offered by both the
Real sources of alternating emf's such as motor alternators or electronic
oscillators will not only have internal resistance but may also have a more
complicated internal impedance . Whatever load is connected to the terminals ,
the voltage V.
