Question

The time rate of change of magnetic flux has the same dimensions of ?
A . Current
B. Magnetic induction
C. Potential difference
D. Resistance

Answer 1

the correct answer is C. Potential difference

by the formula |e| = rate of change of flux

where e= induced emf which has the dimensions same as that of potential difference

Answer 2

Answer:

The time rate of change of magnetic flux has the same dimension of potential difference.

Explanation:

Potential difference ⇒ e=-dФ/dt

e⇒ work/charge=W/Q

                         =ML^2T^-2/AT

                        =ML^2T^-3A^-1

Rate of change of magnetic flux =dФ/dt

                                                       =B*A/t

FA/qvt            =MLT^-2(L^2)/AT(L)

                      =ML^2T^-3A^-1

So, The time rate of change of magnetic flux has the same dimension of potential difference .
