A resistance, inductance & capacitance are connected in
series between points A & B.The voltage drops across the
resistance,inductance&capacitance are found to be
40V,70V&100V respectively. What is the total voltage between
between points A&B (Vab)?
a)210V b)70V c)50V d)230V

Answer Posted / saurabh kumar

50v
bcoz Vc n Vl r in oppsite direction.....so 100-70=30v
n Vr is perpendiculr to resultant of Vc n Vl . . . .
so final resulatnt is 50v....
