Question
In a circuit L, C and R are connected in series with an alternating voltage source of frequency f. The current leads the voltage by 45o. The value of C is : -
Options
A.
B.
C.
D.
Solution
tan 45o = 
⇒ R = 
= 2πfL
⇒ R + 2πfL =
⇒C = 
⇒ R = = 2πfL⇒ R + 2πfL =
⇒C = Create a free account to view solution
