All devices use two wire, the live and the neutral. These carry the current used by the device. Most devices also have an earth wire for safety, which carries no current until a fault occurs and then the fault current in the earth wire might save someone from being electrocuted.
In most electrical devices the neutral wire is connected under the silver coloured screw.
The receptacle that you are looking at might be a 240 volt receptacle and that is the reason, there is no neutral needed. You should be able to tell by the configuration of the blade pattern if it is rated for 240 volt operation.
A neutral wire failure can cause overloaded circuits, electrical fires, and can also result in damage to electronic devices. In some cases, it can lead to electric shocks or power surges within the electrical system. It is important to address neutral wire failures promptly to avoid potential hazards.

The ribs on one side of an extension cord wire typically indicate the "neutral" wire. The neutral wire is responsible for completing the circuit, allowing the electricity to flow back to the power source. It is important to correctly identify and connect the neutral wire to ensure safe and proper functioning of electrical devices.
Some smart home devices that can be installed without a neutral wire include Lutron Caseta Wireless Smart Lighting, TP-Link Kasa Smart Wi-Fi Light Switch, and Leviton Decora Smart Wi-Fi Dimmer Switch.
Typical home wiring will have one hot wire, one neutral wire, and one ground wire per circuit. An open neutral would indicate that the neutral wire, usually white wire, is broken.
If wired properly the ridged wire is the neutral.
The neutral wire is typically colored white or gray.
The hot wire carries current from the source to the electrical device, while the neutral wire carries current back to the source. This completes the circuit and allows electrical devices to function properly. The distinction between the two ensures proper functioning and safety in the electrical system.
The neutral wire and power wire are never connected together.
In an electrical circuit, the white wire is typically designated as the neutral wire.
