Why Diode in Arduino Reset Pin ???

                   The thing is that if you have a capacitor with 5V across it, like when the DTR is zero and the reset is pulled up to 5V and you take that end that has a zero and make it 5V, in that instant the end that...

What is Ferrite Beads , Where it is Used ???

                  An effective method for filtering high frequency power supply noise and cleanly sharing similar voltage supply rails (that is, analog and digital rails for mixed-signal ICs) while preserving high frequency...

What are the Network Bands Used in India for 2G, 3G and 4G ???

               Network frequency bands are often overlooked while purchasing any smartphone. Network bands are important related to coverage and data speed on your mobile. So, we will discuss about different network bands used...

What is the difference between Null Modem cable and Straight Through Cable...???

             The null modem cable is frequently called a Crossover cable. It is used to allow two serial Data Terminal Equipment (DTE) devices to communicate with each other without using a modem or a Data Communications Equipment (DCE)...

What is the difference between DCE and DTE ???

           DTE is the source or destination of digital data, while DCE is the equipment used to transmit or receive the data. DTE stands for Data Terminal Equipment, while DCE stands for Data Communications Equipment.      ...

What are the types of Cooling methods in Transformers ???

                    No transformer is truly an 'ideal transformer' and hence each will incur some losses, most of which get converted into heat. If this heat is not dissipated properly, the excess temperature in transformer...

What are Random wound and Form wound Coils in Electric Motor ??? How they influence the Motor ???

                 A typical low-voltage generator is built with multi turn stator coils, ranging from one to 16 turns per coil. These coils can either be form wound (where the wire is square or rectangular and the turns are...

How Insulation fails in Electric Motor ???

                Moisture and contaminants promote tracking and deterioration that can lead to failure of majority of motors. Tracking failures are caused by small partial discharge currents, which develop localized heating...

Why Aluminium Windings are not being used in Motors ?

(2 Min Read)Resistivity of Copper  is 1.68 x 10-8 OhmResistivity of Aluminium 2.65 x 10-8 OhmAluminium/Copper  = (2.65 x 10-8) / (1.68 x 10-8) = 1.6    Aluminum’s resistivity is 1.6 times higher than copper’s resistivity. To compensate,...

What is Relation between Hardness,Ductility,Malleability&Brittleness...

HARDNESS:  Hardness is a measure of the material’s resistance to localized plastic deformation (e.g. dent or scratch). DUCTILITY:  Ductility measures the amount of plastic deformation that a material goes through by the time it breaks. Ductility is said...

What is Ductile to Brittle Transition...??? How it related to Titanic Sinks...???

                At low temperatures some metals that would be ductile at room temperature become brittle. This is known as a ductile to brittle transition.           The ductile to brittle transition...

What is Magnet wire?

    Magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductors, motors, speakers, hard disk head actuators, electromagnets, and other applications that...
