A home electrical question...
Thought I'd check here as there are a lot of experts that help out. I bought a place that has a light over a stairway, switch at bottom of stairs, switch at top. I noticed that the light is still on...

Quote from Health Canada on the topic of Electric Magnetic Fields (EMFs):
START QUOTE:
EMFs are invisible forces that surround electrical equipment, power cords, and wires that carry electricity, including outdoor power lines.
•Electric Fields: These are formed whenever a wire is plugged into an outlet, even when the appliance is not turned on. The higher the voltage, the stronger the electric field.
•Magnetic Fields: These are formed when electric current is flowing within a device or wire. The greater the current, the stronger the magnetic field.
EMFs can occur separately or together. For example, when you plug the power cord for a lamp into a wall socket, it creates an electric field along the cord. When you turn the lamp on, the flow of current through the cord creates a magnetic field. Meanwhile, the electric field is still present.

The physics of Capacitance is related to Electric Fields.
The physics of Inductance is related to Magnetic Fields.
