Question

write ohm's law and state its SI units

​

Answer 1

Explanation:

According to the ohm's law, the electric current flowing through a conductor is directly proportional to the potential difference applied across its end, providing the physical conditions such as temperature remain unchanged.

It's SI unit is ohm.

Answer 2

Answer:

V= IR

Explanation:

The current flowing through a counductor, such as a metallic wire, is directly proportional to the potential difference across its ends,provided its temperature and other physical conditions remains the same.

If 'I' is the current flowing through a conductor and 'V' is the potential difference (or voltage) across its ends, then according to Ohm's law,

I proportion V (at constant temperature).

This is also written as,

V proportional I

therefore,V=(constant) I

So,V/I= constant

V/I=R

So,V=IR
