Electrical testing and measurement devices can tell you if a circuit or wire is energized as well as tell you how much voltage or current an electrical circuit is carrying. Other types of testing devices can tell you if a network cable is connected properly or if there is continuity in that cable.
Hobbyist & DIY Electronic Devices & Circuits
Everyday electronic items are not just molded from plastic and metal and then shipped to the store for you to buy. Electronics include a huge array of circuits, transistors, resistors, capacitors, etc all arranged perfectly to work together. This specific field of electrical engineering allows devices like the cell phone to work for you when you need to make or receive a call, let you watch tv, or even know what time it is on your digital watch. Electrical Engineering is also involves a study of various machines such as AC DC motors. These common devices are used for many purposes in industry as well as in the domestic sector. Learn about how they work, how they’re built and how they are used in our daily live.
Once you understand basic circuit theory you can even start building your own electronic devices! Find instructions and guides here!
