Question

Is Ohm's law accepted?

Answer 1

Yes, Ohm's Law is widely accepted and considered one of the fundamental principles in electrical engineering and physics. It describes the relationship between voltage (V), current (I), and resistance (R) in a simple linear form:

\[
V = I \times R
\]

In this equation:

1. V is the voltage (in volts),
   

1. I is the current (in amperes),
   

1. R is the resistance (in ohms).
   

Ohm's Law holds true for many materials, particularly those that are linear and have constant resistance (called ohmic materials). For these materials, as the voltage increases, the current increases in direct proportion, which is exactly what Ohm’s Law states.

However, Ohm's Law doesn't apply universally to all materials or conditions. For example:

1. Non-ohmic materials (like semiconductors, diodes, or superconductors) do not follow this linear relationship. In these cases, the resistance can change with voltage or current.
   

1. High-voltage conditions or extreme temperatures might cause deviations from Ohm’s Law.
   

But in general, for typical materials under normal conditions, Ohm's Law is a reliable and well-accepted principle.
