Question

Slate ohms law. Show It mathemaucally. list the factors on which resistance of a cylindrical conductor depends.​

Answer 1

Explanation:

Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

Factors on which the resistance of a cylindrical conductor depends:

(i) Area of a cross-section of the conductor.

(ii) Nature of the material.

• SI unit of resistivity is ohm
