Question

What is ohms law ?give its formula ?is it valid for conductors only ?

Answer 1

Answer:

❤ohms law :-According to ohms law current flowing in a conductor is directly proportional to the potential difference across its ends .

❤ohms law gives three formula:-

• V= IR
• R=V/I
• I=V/R

❤yes ,it is only valid for conductors

hope helps

Answer 2

Answer:

V=I/R

Explanation:BECAUSE  POTENTIAL DIFFERENCE IS DIRECTLY PROPORTIONAL TO CURRENT BUT INVERSELY PROPORTIONAL TO RESISTANCE THEREFORE V=I/R IS OHMS LAW THROUGH WHICH WE CAN UNDERSTAND THE RELATIONSHIP BETWEEN POTENTIAL DIFFERENCE AND CURRENT WHEN THE PHYSICAL STATE OF CONDUCTOR IS CONSTANT
