Alternating CurrentHard
Question
In an AC circuit the potential differences across an inductance and resistance joined in series are respectively 16 V and 20V. The total potential difference of the source is
Options
A.20.0 V
B.25.0 V
C.31.9 V
D.53.5 V
Solution
In any ac (LR) circuit, total potential is give by V = 
where VR and VL are potial across resistance respectiely.
Hence V =
= 25.6V
where VR and VL are potial across resistance respectiely.Hence V =
= 25.6V
