Chapter 1, Problem 76A

To determine

To Give:An example of scientific law

Explanation of Solution

Introduction:

Scientific laws are statements, that explain or predict the natural phenomena by using repeated experiments or observations.

The example of scientific law isOhm's law.

When physicsl state of the conductor such as length, area and temperature,etc. remains same, then current flowing through the conductor is directly proportional to applied voltage across the conductor.

  $I\propto V$

V = voltage or potential difference developed between two ends of a conductor.

I = current flowing through the conductor.

V = I R

Here, R is constant.

R = resistance of a conductor.

This law gives the relationship between current flowing through the conductor and voltage developed between the conductor. Here, the current and voltage are two physical quantities and they are direcly propertional to each under certain conditions as per the Ohm’s law.
