Expert Answer:

 Resistance in any electric wire helps in manipulating the current that is flowing through the circuit. Also, it enables the measurement of current and voltage flowing through a circuit. Furthermore it sometimes helps in saving electric appliances from excess current as the excess current would produce greater heat in the presence of resistance leading to breakdown of circuit at that point.
