The energy transfered to the battery of an invertor from the electric line is given by U=E.q where q = charge transfered. If A is the ammeter reading during transfer for a small time Deltat, then the dimensions of e.m.f. E of the battery are : |

Answer» `ML^(2)T^(-3)A^(-1)` `:.e.m.f.E=(U)/(q)` `E=(ML^(2)T^(-2))/(AT^(1))` `[ML^(2)T^(-3)A^(-1)]` `:. (a)` is the CORRECT choice. |
