what is equivalent resistance and specific resistance .
don't spam guys ...
sahilc72:
Basic differences betweenresistance and specific resistanceare below. Resistance. R = V/I. The ratio of the potential difference between the two ends of a conductor to the current flowing through at uniform temperature is called resistance of that conductor. The unit of resistanceis ohm (Ω).

More resistance means less current is flowing through the circuit. Equivalent resistance is a different way of indicating 'total' resistance, which we calculate differently for series and parallel circuits.

Parallel Circuits. The voltage drop is the same across each parallel branch. The sum of the current in each individual branch is equal to the current outside the branches. The equivalent or overall resistance of the collection of resistors is given by the equation 1/Req = 1/R1 + 1/R2 + 1/R3.
A measure of the potential electrical resistance of a conductive material. It is determined experimentally using the equation ρ = RA/l, where R is the measured resistance of some length of the material, A is its cross-sectional area (which must be uniform), and l is its length. It is measured in ohm-meters.
