JEE Main 2004 Physics question

Physics Alternating Current JEE Main 2004

In an LCR series a.c. circuit, the voltage across each of the components, , and is 50 V. The voltage across the LC combination will be

(1)50 V
(2) V
(3)100 V
(4)0 V (zero)Correct

Answer: (4)

Solution

In a series circuit the voltages across L and C are 180° out of phase. With V, the voltage across the LC combination is $
