What were the theories that led to the laws of thermodynamics?

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.

Group of elements with the same number of valence electrons

How does an insulator stop the flow of an electric current? insulators convert electric energy to other forms of energy
