Yes, it is possible to unplug an electrical appliance without turning off the circuit breaker or switch, as long as the appliance is plugged into a wall outlet or power strip with a plug that you can manually remove. Simply pulling the plug out of the socket will disconnect the appliance from the power source and effectively turn it off.
However, it's essential to exercise caution when unplugging any electrical appliance. Always grip the plug firmly and pull it straight out of the socket to avoid damaging the plug or the outlet. If an appliance has a particularly tight or stuck plug, it's better to turn off the circuit breaker or switch to ensure a safe and hassle-free unplugging process.
If you're dealing with a fixed or hardwired appliance (one that doesn't have a plug), you will need to turn off the circuit breaker or switch to disconnect it from the power supply safely. In such cases, it is best to seek the assistance of a qualified electrician to ensure proper disconnection and safety.
