answered-by-expert Expert Answer
The electrical resistance of an electrical element measures its opposition to the passage of an electric current; the inverse quantity is electrical conductance, measuring how easily electricity flows along a certain path.
 
Devices designed to have definite amounts of electrical resistance; used in circuits to limit current flow or to provide voltage drops are called resistors.
