Hi sir, Flux shall be in 'cos' form, not '- cos' Reason: Flux leads the induced emf (since you used Faraday's 2nd law of electromagnetic induction, I assume it is induced emf, not supply voltage. If it is supply voltage, then using derivative formula would be wrong to consider) So if emf is sine then flux has to be cos. -cos would imply flux lags the emf. Please confirm.
Very good handwriting n proper board writing
sir you are the best concept Deliverer. No doubts left behind after studying your lectures, so thank you so much for your efforts 😍
woww sir ..great session..thank you sir
Very good explanation
