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 […]
