Newton's 2nd law of motion:
Net Force = (mass) x (acceleration) .
The law shows the relationship among an object's mass
and acceleration, and the net force acting on it.
If you know any two of the quantities in the formula,
the law can be used to calculate the third one.
The minimum size copper equipment grounding conductor that is required is ; #4 copper
<h3>Equipment grounding conductor </h3>
An Equipment grounding conductor is a conductive part of ground fault current path which connects the non-conducting metallic parts of the euipment together and also connects the system grounded conductor.
For a copper euipment grounding conductor required to serve a control center connected to a 300 amp over current device the minimum size of copper is #4 copper
Hence we can conclude that The minimum size copper equipment grounding conductor that is required is ; #4 copper.

The correct answer of this question is : From high potential to low potential.
EXPLANATION :
Before going to answer this question, first we have to understand the conventional rule for current flow.
As per the conventional rule of electricity, the current direction is opposite to the direction of electronic motion.
The current flows through a conductor is due to the motion of the free electrons. When the conductor or wire is attached to any electric source, the electrons are drifted towards the positive terminal of the source. Hence, electrons are moving from negative terminal to positive terminal.
As per the conventional rule, the current direction will be from positive terminal towards negative terminal i.e from higher potential to lower potential.
Hence, the correct answer of this question is from higher potential to lower potential .
