Detailed Solution

The SI unit of resistance is ohm which is denoted by the symbol omega,

Ω

.the unit of resistance, ohm, can be defined by using ohm’s law

Resistance = \frac{potential difference}{Current}

\to R = \frac{V}{I}

.
A conductor opposes the flow of current by virtue of resistance. The electrical resistance of an object is a measure of its opposition to the flow of electric current. The resistance of the conductor is numerically equal to the ratio of potential difference across its ends to the current flowing through it. The resistance of a conductor relies upon the following: length, thickness, nature of the material, and temperature, of the conductor..
