Is ohms law a universal law .Give examples to illustrate ur ans?
Answers
No ohms law is not a universal law as it's a kind of fundamental law.
The reasons are mentioned below :
- It's said that it's applicable for those devices where the ratio of voltage correspondence to current is usually constant over a huge area of potential differences.
- So there are many electronical devices and conductors which don't obey this fundamental law.
- So the correct definition of Ohm's Law is that if the current passing through any conductor is directly proportional to potential difference applied through it's ends and all the physical factors are constant throughout.
Answer: No
Explanation: Universal laws don't change from different factors
Like universal gravitation constant never changes from any factors
But ohm's law change like from temperature
