Electrical resistance - Simple English Wikipedia, the free encyclopedia

# Electrical resistance

### From Simple English Wikipedia, the free encyclopedia

Electrical resistance is the repulsion of a current within a circuit. It explains the relationship between voltage and electrical current.

Resistance, discovered by Georg Simon Ohm, is the ratio between voltage and current. Ohm's law stated that the voltage between any two points in a conductor changes directly as the current between the two points, given the temperature remains constant. He came up with the equation:

which models the ratio, where:

  R is the resistance of the object, measured in ohms (Ω)
  V is the voltage across the object, measured in volts (V)
  I is the current going through the object, measured in amperes (A)

## [edit] Applications

A resistor is a real life application of electrical resistance.
