Circuit Solution Methods (By Examples)

To find the equivalent resistance between A and B.After marking the junction Hence equivalent resistance between A and B is RAB = 3R/5. Nodal analysis: To find the current distribution in armsTo solve this one must assume the potential of one node equal to zero and then corresponding other potentials as marked in following diagramThe solving equation for Read more about Circuit Solution Methods (By Examples)[…]


Explanation Of S – Block (Group II A Elements)

Group IIA Elements: Beryllium (Atomic number – 4) Magnesium (Atomic number – 12) Calcium (Atomic number – 20) Strontium (Atomic number – 38) Barium (Atomic number – 56) Radium (Atomic number – 88)  Have 2 electrons in the outermost orbit.  By loosing two electrons they form stable + 2 ions.  They are divalent and show Read more about Explanation Of S – Block (Group II A Elements)[…]


Wondering how leaves are arranged on the stem! Then Check it out…………… Phyllotaxis or phyllotaxy is the arrangement of leaves on a plant stem. Which originates from a Greek word   phýllon “leaf” and  taxis “arrangement”. The basic arrangements of leaves on a stem are opposite, or alternate = spiral. Leaves may also be whorled if Read more about PHYLLOTAXY[…]

Free, Forced, Damped and Resonant Vibrations

Free Vibrations: If a given body is once set into vibrations and then let free to vibrate with its own natural frequency, the vibrations are said to be free vibrations. The natural frequency of free vibrations depends on the nature and structure of the body and in ideal situation, the amplitude, frequency and the energy Read more about Free, Forced, Damped and Resonant Vibrations[…]

Hello MyRankers, here is the explanation of YOUNG DOUBLE SLIT EXPERIMENT 1. In Young’s double slit experiment, if monochromatic light is replaced by white light then central fringe will be white; all other fringes will be coloured. White light consists of colours between violet and red (VIBGYOR). Wavelength λ is the shortest for violet light and Read more about YOUNG DOUBLE SLIT EXPERIMENT[…]


Thermo dynamics

Ever wondered why Thermo Dynamics is named so? THERMO → Heat, Dynamics → Motion or flow Basically, thermodynamics deals with all changes in energy or transfers of energy that accompany physical and chemical processes. Important terms in Thermo Dynamics:   System, surrounding and Boundary: A system is defined as specific part of matter which is under experimental investigation and the Read more about Thermo dynamics[…]
