Question

QNo.1 (a) State and explain ohm's law.​

Answer 1

Answer:

Ohm's Law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged.

That can be written as

I ∝ V

Thank you

Answer 2

Explanation:

Resistance , it is the ability of a conductor to oppose the flow of current.... Therefore resistance is directly proportional to

• resistivity
• Length of the conductor

and inversely proportional to

• Area of cross section

R= p L
