No, $\frac{x}{x}$ is not always equal to 1. It depends on the value of x.

$$\frac{x}{x} = \begin{cases} 1, & \text{if } x \neq 0 \\ \text{undefined}, & \text{if } x = 0 \end{cases}$$So, $\frac{x}{x}=\mathrm{1\; when <strong\; data-start="585"\; data-end="635"\; style="font-family:\; Verdana,\; Arial,\; Helvetica,\; sans-serif;"><br></strong>}$$x \neq 0$.

No, $\frac{x}{x}$ is not always equal to 1.

• For any non-zero number x:

  $$\frac{x}{x}=1$$

  Example:
  $\frac{5}{5} = 1$, $\frac{-3}{-3}=$1

• For $x = 0$:

  $$\frac{0}{0}\text{ is undefined}$$

Division by zero is not defined in mathematics.

Electrons and Electricity

Electrons: These are particles that exist in the outer "shells" of atoms. In certain materials like metals (conductors), some electrons are "free" to move from one atom to another.

Electric Current: When a force (voltage) is applied, these free electrons drift in a specific direction through a conductor (like a copper wire). This movement is what we call electric current.

Power Vs Energy 

In physics and electrical engineering, the distinction between energy and power is a matter of capacity versus rate.

Energy: is the total amount of work a system can perform or the total quantity of "fuel" consumed over a period of time. It is a cumulative measure.

Power: on the other hand, is the instantaneous rate at which that energy is being used or transferred. It describes how fast the work is being done at any given moment.

Electricity is essentially the flow of electrons, which are tiny, negatively charged particles within atoms; in conductive materials, an external energy source pushes these loosely bound outer electrons to move from atom to atom, creating an electric current, the directed movement of these charges that powers our devices, though the conventional current direction is opposite to the actual electron flow
