Why, `CO_(2)` is considered as excellent extinguisher in case of fire involving electrical equipment? Explain.

Explanation

**Step-by-Step Solution:**

1. **Understanding Fire**: Fire requires three essential components to ignite and sustain: fuel, heat, and oxygen. This is often referred to as the "fire triangle."

2. **Role of CO₂**: Carbon dioxide (CO₂) is an effective fire extinguisher because it can disrupt this fire triangle. When CO₂ is released, it envelops the fire.

3. **Cutting Off Oxygen Supply**: By surrounding the flames, CO₂ effectively displaces the oxygen in the vicinity of the fire. Since oxygen is a crucial element for combustion, reducing its availability helps to extinguish the fire.
