Question

define is ohms 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.

Answer 2

Ohm's law gives a relationship between current and potential difference.

According to Ohm's law, at a constant temperature the current flowing through a conductor is directly proportional to the potential difference across its end.

From this relation we can conclude that:

• The current is directly proportional to the potential difference.
• The current is inversely proportional to the resistance.

Since the current is directly proportional to the potential difference applied across the ends of a conductor it means that if the potential difference across the end of a conductor is doubled, the current flowing through it also get double and if the potential difference is halved the current also gets halved.

On the other hand the current is inversely proportional to the resistance so if the resistance is doubled the current gets halved and if the resistance is halved then the current gets doubled.

The strength of an electric current in a given conductor depends upon 2 factors:

• Potential difference across the end of conductor.
• Resistance of the conductor.
