1.	The phase diffenernce between the alternating current and emf is `(pi)/(2)`. Which of the following cannot be the constiuent of the circuit?A. L aloneB. LCC. R,LD. C alone
Answer» Correct Answer - C L,C or LC can produce a phase difference of `(pi)/(2)` between alternating current and e.m.f. but it R is present, then the phases difference will lie between 0 and `(pi)/(2)` but it will not be `(pi)/2`.
