The resistor is small enough so that the load could always receive somewhat more than the maximum current it would ever need. The shunt regulator is placed across the load and conducts excess current around the load such that the voltage across the load remains a constant as the load draws the actual current at any given time. A common shunt regulator is a Zener diode which is an example of an open loop system. Feedback control can also be used to drive the current through the control element (a transistor) across the load. Shunt regulators are generally only used for low power applications because they can be very inefficient. However, shunt regulators have an inherent fault current limiting feature and also can regulate even if the load is forcing current into the regulator rather than drawing current from it. Shunt regulators also have an interesting feature that the input current is constant – independent of load current (except if a load fault occurs – but that is a special case not in normal operation). Thus shunt regulators are very good at isolating a load with rapid and large current fluctuations.

This forward-bias voltage drop exhibited by the diode is due to the action of the depletion region formed by the P-N junction under the influence of an applied voltage. If no voltage applied is across a semiconductor diode, a thin depletion region exists around the region of the P-N junction, preventing current flow.

This then is the motor’s natural speed-torque curve. Below a certain speed, called the corner speed, current would rise above the motor’s rated current, ultimately to destructive levels as the motor’s speed is reduced further.

Completing an electrical engineering degree and then getting a job in the field means you will see a lot a lot a lot of these schematics. It’s important to understand exactly what is going on with these. While they can (and will) get very complex, these are just a few of the common graphics to get your footing on.

In addition to reading this instructable it may be a good idea for you to read my other instructable "electronics components and what they do" to get a good understanding of what you are doing when building a project.
By Cyrielle Marjolaine. Circuit. Published at Tuesday, December 19th 2017, 00:33:07 AM. Since single-layer/single-sided PCBs only have their various circuits and electrical components soldered onto one side, they are easy to design and manufacture. This popularity means that they can be purchased at a low-cost, especially for high-volume orders. The low-cost, high volume model means they are commonly used for a variety of applications, including calculators, cameras, radio and stereo equipment, solid state drives, printers and power supplies.
By Cyrielle Marjolaine. Diagram. Published at Tuesday, December 19th 2017, 00:21:22 AM. A PCB Layout is the resulting design from taking a schematic with specific components and determining how they will physically be laid out on a printed circuit board. To produce a PCB Layout, you must know the connections of components, component sizes (footprints), and a myriad of other properties (such as current, frequencies, emissions, reflections, high voltage gaps, safety considerations, manufacturing tolerances, etc.).
By Bertille Solange. Diagram. Published at Monday, December 18th 2017, 23:06:24 PM. There are drawing programs, and there are schematic capture programs. All schematic capture programs will produce output for inclusion in publications. However, these programs have different goals, and it shows. Rarely is the output of a schematic capture program really suitable for publication; often it is not even readable, or cannot be scaled. Engineers who really want to have a useful schematic drawing of a circuit usually redraw the circuit in a general drawing program, which can be both tedious and prone to introducing new errors.
