Here and below also the term “emf” is the magnitude of the emf. In this equation we have learnt that the equation N = 1 and the flux denoted by Φ = BA cos θ. We have already seen a symbol denoted by letter or symbol θ = 0º and cos θ = 1 since B is perpendicular to...
In this equation, N = 1 and the flux Φ = BA cos θ. We have θ = 0º and cos θ = 1, since B is perpendicular to A . Now ΔΦ =Δ(BA) = BΔA, since B is uniform. Note that the area swept out by the rod is ΔA = ℓΔx. Entering these quantities into the ...

Limit of Current: In the equation V = E – Ir if the magnitude of I or r is very high then the magnitude of V becomes very small. If Ir becomes equal to E, then V = 0 . Thus the cell cannot produce any potential difference in the external circuit. So, for every cell I has a...

That should be R+r in that last equation, since you are adding +r to both sides of the equation before it. I=(emf/(R-r)) I=(7.99/((23+.555)-.555))) R is simply 23 ohms, not 23+.555 I=0.34739 V=IR V=(0.34739)(23.555) V=8.182802174 INCORRECT Nov 1, 2011 #3 ugod...
