In an circuit the potential differences across an inductance and resistance joined in series are respectively (16 \mathrm{~V}) and (20 \mathrm{~V}). The total potential difference of the source is
Options
- A(20.0 \mathrm{~V})
- B(25.6 \mathrm{~V})
- C(31.9 \mathrm{~V})
- D(53.5 \mathrm{~V})
Correct answer
B. (25.6 \mathrm{~V})
Step-by-step solution
(V_L=16 \mathrm{ V}, V_R=20 \mathrm{ V}).
In the inductor the current lags by (\frac{\pi}{2}).
