________ is a safety wire which protects us from electric shocks and electric fire. 

The correct answer is Earth wire.Key Points

• Earth Wire:
  • The earth wire, also known as the grounding wire, is designed to protect users from electrical shocks and electrical fires.
  • It provides a path for electrical current to flow safely to the ground in case of a fault, such as a short circuit.
  • This helps prevent the buildup of voltages that could cause electric shocks or fires.
  • It is an essential component in electrical safety systems, ensuring that any leakage current does not cause harm to users.

Additional Information

• Neutral Wire:
  • The neutral wire carries current back to the power source to complete the circuit.
  • It is typically at zero volts, but it does not provide the safety features of an earth wire.
• Live Wire:
  • The live wire carries the current from the power source to the load.
  • It is at a high voltage and can be dangerous if touched directly.
