Step 1
Resistance of a conductor is its extrinsic property which depends on dimensions of the conductor. Hence conductor of different dimensions of the same material will have different resistance. Its formula is given as follows:
R is the resistance
l is the length of the conductor
A is the area of cross-section
is the resistivity of the conductor
Step by step
Solved in 2 steps
