Answer 1

Answer:

Specific Resistance is defined as the resistance offered by a unit length and unit cross section area of the material when a known voltage is applied at its ends. Mathematically,

ρ=

l

RA

Therefore, it's units will be

m

ohm×m

2

=ohm m.

Answer 2

Answer:

Secific Resistance is also known as Resistivity.

It is by 'p'. The specific resistance of a material as the resistance of it's specimen of unit lenght and unit area of cross section. Mathematically p = Ra /l.

p = Specific resistance

R = Resistance

a = Cross section area

l = lenght
