Chapter: ELECTROMAGNETIC WAVE What is em wave ? how it is produced ?and all kind of feature are explained here. The propagating in space through electric and magnetic field varying in space and time simultaneously are called electromagnetic wave . Origin – The electro magnetic wave are produced by an accelerated and deaccelerated charge or […]
Projectile motion Projectile given horizontal projection and projectile given angular projection In this topic we will discuss about projectile given horizontal and projectile given angular projection. And we will derive the expressions for equation of trajectory, time of flight , vertical height , horizontal range and velocity of projectile at any time . Projectile motion- […]
OSCILLATION IN AN LC – CIRCUIT LC- oscillation —- An LC circuit consists an inductor and a capacitor connected in parallel . Its another name is tank circuit. Working – At t= 0 – – capacitor is first charged . The whole energy is stored in the capacitor which is U= ½ CV2 , at […]
PHASOR DIAGRAM- PHASORS AND PHASOR DIAGRAM- The co-planar vectors which represents sinusoidal time varying quantities like alternating current or alternating voltage are known as phasor and the graphical representation of these quantities for the ac circuit is known as phasor diagram. In another words we can say when AC or alternating voltage represented as rotating […]
