Electrical power – it surrounds us wherever we go. In our homes, we have a seemingly endless supply
of electricity. Every electrical outlet represents another dynamic source of energy to power our many devices. A new air conditioner – plug it in. A new TV – plug it in. A new microwave oven – plug it in.
Moreover, we are constantly on a quest for more – an Xbox here, a surround sound system there. Of
course, there are limits to the amount of electricity that you can put on any one circuit in your home before
the circuit breaker trips and everything on that circuit stops. That is why we have multiple circuits; it
enables us to plug in even more devices until we reach the limit of energy being supplied to us. Unfortunately,
we do not have a dedicated power source for our homes; it is more like a 1940’s telephone party
line: we must share it with all of our neighbors.
