Many years ago, I had my stereo on, and when I tried to switch tracks on the CD player (using the remote) the lights in the room dimmed. When I turned the switch on the lamp, the stereo went off. Then I heard a strange clicking noise from the other end of the house, and found my computer making strange noises. Every time I flipped a switch, another area of the house would be affected. It took the electric company several hours to discover one leg of my power mains was loose in the junction box on the corner of my lot, so my house was only getting partial power. Every time I closed a switch, it would draw down the current somewhere else in the circuit.
