There is a panel with two electrical outlets in the corner of my room. Four cords share these two outlets. They are chords for my electrical toothbrush charging stand my phone charger, a floor fan, and the lamp. I need to use these electrical items at different times of the day so I’m always playing musical chairs with the outlets sometimes I have some of the items r Running that are already plugged in. But I want to plug in something else for example if I have the lamp on and the fan on but I need to charge my phone. Tonight I was in the situation I had the lamp I had the fan going and the lamp and the fan or both plugged in I wanted to keep the fan plugged in because it was hot and I was about to turn off the light for the night but I need to charge my phone so I wanted to unplug the lamp the only problem is both the cords are black and they look the same usually I follow the cord along their paths to find out which one is going to the electrical appliance that I don’t mind unplugging tonight I looked at the two cords there and I didn’t have any patience for some reason so I just unplugged one and I looked at the fan to see if it would go off but it did not he kept blowing so it must’ve been the lamp that I am float I had guessed correctly.
