Question

Explain the term resistance of the conductor ? Name two metals which offers very high and low resistance? Write the factor in which resistance of the conductor depend ?

Answer 1

the ability of an conductor to oppose heat is called resistance factors depend on resistance are 1.length of a conductor
As the length of the conductor increases resistance increases
2. area of the conductor
As the area increases value of resistance decreases
3.Temperature of the conductor
As the temperature increases resistance increases
4. nature of the material

Answer 2

resistance is the opposition offered by the conductor to the flow of current in the circuit
the metal that offers low resistance are silver and copper while the metal that offers high resistance are generally alloys
FACTORS RESISTANCE DEPEND UPON :
area of cross section
length
nature of the material
temperature
RESISTANCE IS DIRECTLY PROPORTIONAL TO LENGTH
WHILE INDIRECTLY PROPORTIONAL TO AREA OF CROSS SECTION
