What is Coulomb’s Law?

The law can be written mathematically as:

F = kq1q2/r^2

Where:

The magnitude of the force between charges is denoted by F, while q1 and q2 represent the magnitudes of the respective charges.

r is the distance between the charges

k is the Coulomb’s constant

So in plain English, as the distance increases, the force decreases rapidly as an inverse square relation. But if the charges increase, the force increases linearly.

Note that this fundamental law allows us to compute the forces between charges in any electrical engineering application imaginable. But the formula looks complicated, so how can we easily use it? Enter…the Coulomb’s calculator!

Coulomb’s Law Calculator Usage Tips

To properly use Coulomb’s Calculator, keep these tips in mind:

Make sure all units are consistent. Use Coulombs (C) for charge and meters for distance.

Enter charge values as positive or negative to indicate repulsive or attractive force. Like charges are positive and negative.

The electrostatic force calculated is a vector quantity with direction. Imagine a straight line connecting the two charges.

For multiple charges, you can sum up the individual forces from each pair interaction.

For distributed charges over an area, integrate the charge to get the total q value.

For point charges (like electrons), make sure to enter very small distances like nano or micrometers.

With the ability to easily calculate electric force, you can gain deeper insights into electrical systems. The Coulomb’s calculator makes it a breeze!

What are Coulomb’s Law Fun Facts? 

In delving into the intricacies of Coulomb’s Law, the enthralling historical narrative and captivating personalities contributing to this foundational physics concept often elude our grasp. The deployment of Coulomb torsion balances in the initial gauging of the electrostatic constant k serves as an evocative testament to the journey through the arcane corridors of early measurements. These novel instruments applied twisting forces to measure tiny electrical forces.

Coulomb originally wrote his law with forces in Newtons, but charge in ‘unites de charge’ rather than Coulombs. The Coulomb unit was named later in his honor.

The electrostatic constant k equals about 9 × 109 N·m2/C2. This constant reflects the property of space/vacuum to permit electric forces.

Coulomb studied friction and viscosity forces years before investigating electrostatics. He determined the mathematical laws governing both sliding and viscous friction.

As well as physics, Coulomb also contributed greatly to applied mechanics and civil engineering. He invented the Coulomb damper and studied stability and fractures.

The next time you use Coulomb’s calculator, remember the fascinating history behind it! Charles Coulomb’s pioneering work made modern electrical engineering possible.
