A resistor is a two-terminal electronic component which
implements electrical resistance as a circuit element. When
a voltage V is applied across the terminals of a resistor,
a current I will flow through the resistor in direct
proportion to that voltage. The reciprocal of the constant
of proportionality is known as the resistance R, since,
with a given voltage V, a larger value of R
further "resists" the flow of current I as given by Ohm's
law
