An ac source of 100 Hz is connected with series combination of a resistance, a capacitor and an inductor. If potential difference across elements is 46, 8 and 40 volt respectively then value of ac emf source is :- |
(1) | 94 | (2) | 14 | (3) | 10 | (4) | 76 |
Here the emf of the ac source would be
E = 46 V + 8 V + 40 V = 94 V
which is option (1).
