A video explaining the circuits that are used in home wiring – series and parallel as well as combination circuits, sometimes referred as complex circuits. Examples given how to wire some simple house circuits using the basics given. Also covered, an explanation on three and four way switches – they are not that complex! With my method – they are a piece of cake.
Next up – Ohms Law – how to calculate current and wattage, how do you measure or calculate power consumption, with some real world solar examples to make it all interesting!
Good site on the basics (and then some) of electrical circuits:
