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

Explanation

\frac{x}{x} = 1 \quad \text{**only when** } x \neq 0

Why?

• If x \neq 0:
  \frac{x}{x} = 1
  (Any non-zero number divided by itself equals 1)
• If x = 0:
  \frac{0}{0}
  This is undefined in mathematics (division by zero is not allowed).

Final Conclusion

\boxed{\frac{x}{x} = 1 \text{ for all } x \neq 0}

So, it is NOT always 1, because at x = 0 the expression has no value.

Electrons, Electricity, and Energy

Electrons: Tiny particles with a negative charge, orbiting atoms. In wires, specific "free" electrons (valence electrons) can move.

Electricity: The directed movement or flow of these free electrons through a conductor, like a wire, driven by a force (voltage).

Energy: The ability to do work, like lighting a bulb or heating a room. Electrical energy is the energy from moving charges and can be stored (batteries) or converted (heat, light). 

Energy (E): The total work done or total energy consumed.Formula: Energy = Power × Time (\(E=P\times t\)).Units: Joules (J), Watt-hours (Wh), or kilowatt-hours (kWh).

Power (P): The rate at which energy is used or transferred (Energy per unit time).Formula: Power = Energy / Time (\(P=E/t\)).

Units: Watts (W) or Joules per second (J/s).

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.
