resistance and flux

It is clear that non-violent resistance is a mode of action in need of justification and limitation in Christian morality, like any other form of resistance.
and again, that `` the object of non-violent resistance is partly analogous to this object of war -- namely, to demoralize the opponent, to break his will, to destroy his confidence, enthusiasm, and hope.
In another respect it is dissimilar, for non-violent resistance demoralizes the opponent only to re-establish in him a new morale that is firmer because it is based on sounder values ''.
A trial of strength, however, is made quite inevitable by virtue of the fact that anyone engaging in non-violent resistance will be convinced that his action is based on sounder values than those of his opponent ; ;
resistance and proportional
Ohm's law is a basic law of circuit theory, stating that the current passing through a resistance is directly proportional to the potential difference across it.

File: Georg Simon Ohm3. jpg | Georg Ohm ( 1789-1854 ): found that there is a direct proportionality between the electric current I and the potential difference ( voltage ) V applied across a conductor, and that this current is inversely proportional to the resistance R in the circuit, or I = V / R, known as Ohm's law, namesake of the unit of electrical resistance ( the ohm )
Ohm's law states that the voltage ( V ) across a resistor is proportional to the current ( I ), where the constant of proportionality is the resistance ( R ).
This formulation states that the current ( I ) is proportional to the voltage ( V ) and inversely proportional to the resistance ( R ).
