Question

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

Answer 1

Here the emf of the ac source would be

E = 46 V + 8 V + 40 V = 94 V

which is option (1).
