In our daily lives, sockets play an indispensable role as a bridge between our appliances and power supply. But have you ever noticed the mysterious letter logos on the sockets – L and N? What do they represent? What are the secrets of household electricity? Today, let's find out and take you into the world of electricity behind the socket!
1. L and N: mysterious symbols on the socket
When you pick up a household socket and look closely, it is not difficult to find that it is marked with the letters L and N. For most people, these letters may just be decorations on the outlet, but in reality, they carry important electrical information.
- L: Symbol of the line of fire
L, the full name is Live Wire, which stands for Live Wire. In the circuit, the live wire is the main line that transmits electrical energy, it carries the voltage, and is the key to the normal operation of electrical appliances. When we plug in the plug, the live wire is connected to the power cord of the appliance through the socket to provide the required power to the appliance.
- N: The role of the zero line
N, or Neutral Wire, stands for Neutral Wire. The neutral wire plays the role of reflow in the circuit, which conducts the residual current after the use of the appliance back to the power supply, forming a complete circuit cycle. Unlike the live wire, the neutral wire is not charged under normal conditions, ensuring the safety of electricity use.
