The same effect causes a slight decrease in torque with speed in the constant torque region as well. Finally, there is a rounding of the torque curve at the corner speed because the drive gradually transitions from being a current source to being a voltage source. The drive limits current to the motor below the corner speed and thus is a current source. Above the corner speed, the motor’s inductive reactance limits the current and the drive becomes a voltage source as it applies all of the power supply voltage to the motor.

While electrical is the basis of everything, electronic is a subset of electrical. An electrical circuit deals with just the flow of electrons and has components like resistors, inductors and capacitors and uses Alternating Current Source; while electronic circuit deals with the transformation of current and controlling the motion of the electrons and uses Direct Current Source. An electrical circuit is termed as Passive because it doesn’t have any such component that reacts to the current/voltage that passes through them and electronic circuit is called active because of the additional components like diode or a transformer that react to the current/voltage that passes through.

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 Lydie Honorine. Diagram. Published at Tuesday, December 19th 2017, 12:45:48 PM. An electronic circuit is a circular path of conductors by which electric current can flow. A closed circuit is like a circle because it starts and ends at the same point forming a complete loop. Furthermore, a closed circuit allows electricity to flow from the (+) power to the (-) ground uninterrupted.

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 Jessica Mireille. Circuit. Published at Tuesday, December 19th 2017, 02:08:03 AM. Electric current is the rate at which electric charge flows through a given area. Current is measured in the unit of Coulombs per second, which is known as an ampere (A). In an electronic circuit, the electromagnetic problem of currents is typically simplified as a current flowing through particular circuit components.
By Sasha Sara. Amplifier. Published at Tuesday, December 19th 2017, 02:01:05 AM. An input signal will cause the transistor to operate as normal in its Active region thereby eliminating any crossover distortion which is present in class B configurations. A small Collector current will flow when there is no input signal but it is much less than that for the Class A amplifier configuration.
