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.

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across those two points. It means that more the resistance lesser current would flow. I=V/R This would apply to any component of a circuit. For example conductors would increase the current flow and the inductors would decrease it.

By Charlotte Myriam. Circuit. Published at Monday, December 18th 2017, 13:45:45 PM. First let’s understand the difference between these two terms. 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.

If there’s something on a schematic that just doesn’t make sense, try finding a datasheet for the most important component. Usually the component doing the most work on a circuit is an integrated circuit, like a microcontroller or sensor. These are usually the largest component, oft-located at the center of the schematic.

By Charlotte Myriam. Diagram. Published at Monday, December 18th 2017, 12:40:04 PM. The unloaded PCB appears green because thin sheets of green plastic have been applied to both sides (otherwise the PCB would appear pale yellow). Called solder masks, these sheets cover all exposed metal other than the component pads and holes so that errant solder can not inadvertently short (or electrically connect) the printed wires. All metal surfaces other than the exposed pads and holes (i.e., the wires) are underneath the solder mask. Not infrequently, blue or even red solder masks are used.
By Jessica Mireille. Amplifier. Published at Monday, December 18th 2017, 11:38:21 AM. The Class AB Amplifier is a compromise between the Class A and the Class B configurations above. While Class AB operation still uses two complementary transistors in its output stage a very small biasing voltage is applied to the Base of the transistor to bias it close to the Cut-off region when no input signal is present.
