Q & A

What is the purpose of a neutral wire in an electrical circuit?
-The neutral wire in an electrical circuit provides a return path for current back to the source, ensuring that the circuit is complete and allows electricity to flow.
Why do birds sitting on electrical wires not get electrocuted?
-Birds do not get electrocuted while sitting on electrical wires because they are only touching one wire and are not completing the circuit. For electrocution to occur, they would need to touch another wire or the ground, providing a path for the current to flow through their bodies.
What happens if a person touches both a live wire and a neutral wire?
-If a person touches both a live wire and a neutral wire, they complete the electrical circuit, allowing current to flow through their body, which can result in electrocution.
Why are the live wire, neutral wire, and earth wire usually color-coded?
-The live wire, neutral wire, and earth wire are color-coded to ensure safety and to help distinguish between them during installation and maintenance. Typically, the live wire is red, the neutral wire is black, and the earth wire is green or yellow.
What is the function of the earth wire in an electrical system?
-The earth wire provides a path for electrical current to the ground in case of a fault, which helps protect users from electric shock and prevents electrical fires.
How can electrical power theft occur by manipulating the neutral wire?
-Electrical power theft can occur by manipulating the neutral wire to bypass the electricity meter, making it seem like less electricity is being used than actually is, thus reducing the recorded usage and the bill.
What is the role of a transformer in an electrical distribution system?
-A transformer in an electrical distribution system steps down the high voltage from transmission lines to a lower voltage suitable for household or commercial use, ensuring safe and efficient power distribution.
Why is it dangerous to touch an overhead transmission line?
-It is dangerous to touch an overhead transmission line because it carries high voltage electricity. Touching it can complete the electrical circuit through your body, leading to severe electric shock or death.
What measures do electricians take to avoid electric shock while working?
-Electricians use insulating gloves, tools with insulated handles, and ensure they are not grounded by standing on insulating mats or wearing rubber-soled shoes to avoid electric shock while working.
How does a power factor correction device save electricity?
-A power factor correction device saves electricity by improving the power factor of electrical equipment, reducing the amount of reactive power, and making the electrical system more efficient. This leads to lower electricity consumption and reduced energy costs.
