MHB How the charge is conserved in a closed loop circuit?

Click For Summary
Charge conservation in a closed loop circuit is governed by the charge conservation law, which is a consequence of Maxwell's Equations. In differential form, this law is expressed as the equation ∇·J = -∂ρ/∂t, indicating that the divergence of current density (J) is equal to the negative rate of change of charge density (ρ) over time. This relationship ensures that charge does not accumulate in a closed circuit, maintaining a constant flow of charge. The discussion emphasizes the fundamental principles of electromagnetism that underpin the behavior of electric circuits. Understanding this conservation principle is crucial for analyzing circuit dynamics.

It is consequence of the charge conservation law [consequence of Maxwell's Equations...] that in differential form is written as...

$\displaystyle \nabla\ J = - \frac{\partial \rho}{\partial t}\ (1)$

Kind regards

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
