Alternating Current | Revision Checklist 38 for JEE Main & NEET

Alternating Current is one among the important topics of JEE Main which is based on the section of electromagnetism and it requires basic fundamental knowledge of all the topics of electrostatics, capacitance, current electricity, magnetic effects and electromagnetic induction.
In this checklist video of alternating current, Ashish Arora Sir has covered all the aspects of the topic from the point of view of JEE Main, JEE Advanced as well as NEET. All the point wise sub topics of checklist are based on the questions asked in previous year JEE Main and NEET and all these topics cover most of the concepts on which questions can be framed in upcoming exams. This video lecture includes below mentioned concepts and topics.
1. RMS and Mean value of AC Current
2. Different types of AC waveforms
3. Circuit components across and AC emf
4. Resistance, Capacitance and Inductance across AC emf
5. Reactance and Impedance in AC circuits
6. RL, RC and LC AC Circuits
7. RLC Series circuit and Resonance
8. Quality factor and Selectivity of RLC circuit
8. Parallel RLC Circuit
9. Transformer
10. Transformer losses

Ya it would be +\- π/2 depending on whether Xc is greater or X¡_ ... I too had that confusion, so i just searched for LC circuits but found no good content on it, later from books i clarified it out...!!

@@madhavshukla1570 but i guess exactly +/- pi/2 ni hoga because there will be some effect of capcitance if inductance is leading and vise versa Please let me know ....if you agree with what I am thinking.

@@PratyanshiSharmaraag they 2 are opposite vectors lying perpendicular to x axis, either of them can be greater but the angle from x- axis would remain same na 90° (+/-) and coz there is no resistance so we need not to take out that resulting vector by Pythagoras application.....Hope it clarifies 😅😂 Or else go for this link:- kzbin.info/www/bejne/jXyypZyalJKrkJo
