A) \[Q=\frac{\Delta \,\phi }{\Delta \,t}\]
B) \[Q=\frac{\Delta \,\phi }{\Delta \,t}\times R\]
C) \[Q=-\frac{\Delta \,\phi }{\Delta \,t}+R\]
D) \[Q=\frac{\Delta \,\phi }{R}\]
Correct Answer: D
Solution :
(d) \[Q=\frac{\Delta \,\phi }{R}\] We know that \[\varepsilon =\frac{d\phi }{dt}\] But \[\varepsilon =lR\] and \[l=\frac{dQ}{dt}\Rightarrow \frac{dQ}{dt}R=\frac{d\phi }{dt}\Rightarrow dQ=\frac{d\phi }{R}\] or \[\Delta Q=\frac{\Delta \,\phi }{R}\]You need to login to perform this action.
