The concept of the radian specifically however, is credited to Roger Cotes who described the measure in 1714. History/origin: Measuring angles in terms of arc length has been used by mathematicians since as early as the year 1400. One radian is equal to 180/π (~57.296) degrees. An angle's measurement in radians is numerically equal to the length of a corresponding arc of a unit circle. It is a derived unit (meaning that it is a unit that is derived from one of the seven SI base units) in the International System of Units. Radianĭefinition: A radian (symbol: rad) is the standard unit of angular measure. History/origin: The term "minute" is derived from the Latin "pars minuta prima" which means the "first small part." The minute was originally defined as 1/60 of an hour (60 seconds), based on the average period of Earth's rotation relative to the sun, known as a mean solar day.Ĭurrent use: The minute, as a multiple of the second, is used for all manner of measurements of duration, from timing races, measuring cooking or baking times, number of heart beats per minute, to any number of other applications. Under Coordinated Universal Time, a minute can have a leap second, making the minute equal to 61 rather than 60 seconds. all are available here.Definition: A minute (symbol: min) is a unit of time based on the second, the base unit of the International System of Units (SI).
Speaker’s All types of speakers with different types of variety.Audio signal and amplifies the signal to help your speakers play the audio.

PIC or DSPIC DSPic is a much more advance controller chip than a regular PIC.The BJTs are again classified into NPN and PNP transistors. Transistors are basically classified into two types they are Bipolar Junction Transistors (BJT) and Field Effect Transistors (FET). TRANSISTOR & MOSFET All types of Transistor and Mosfet are available on Nex Electronic at Best Price.Connectors & Plugs All type of Header: Male Header, Female Header, Dc Connectors, AC connectors, Fuse, USB, Power Connector, IC Connectors, etc.CASES & CABINETS All type of case & cabinet for arduino, Raspberry Pi, SMPS cabinet, Stabilizer cabinet, all are available here.IC (Integrated Circuit) There are numerous types of ICs among which, an IC will function as a timer, counter, register, amplifier, oscillator, logic gate, adder, microprocessor, and so on.Crystal Oscillator All type of Crystal Oscillator: Colpitts Crystal Oscillator, Pierce Crystal Oscillator, Butler Oscillator, Tri-tet Oscillator.Active Components All types of components like Inductors, Variable Resistors, Diodes, Potentiometer, Buzzer/Speakers, Thermistor, etc.
