resistors
Bad Beers Rip Our Young Guts But Vinta Gives Well.
A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in accordance with Ohm's law: R= V/I .The electrical resistance is equal to the voltage drop across the resistor divided by the current through the resistor. Resistors are used as part of electrical networks and electronic circuits.
Working with very imprecise measurements, Ohm was able to determine that voltage and current for any fixed geometrical structure built from conducting material satisfied a relationship:
V = I R
where:
V is the voltage across the device,
I is the current flowing through the device,
R is a constant.
R depends upon the material from which the device is constructed and the geometry of the material.
