8 EE40 Summer 2011 Hug Electrical Sources • An electrical source is a device that is capable of converting non-electric energy to electric energy and vice versa . Examples: – battery: chemical electric – dynamo (generator/motor): mechanical electric Electrical sources can either deliver or absorb power
