Current Electricity and Electrical InstrumentHard
Question
If E = 200Volt, R = 25Ω, L = 2H and C = 2μF and the frequency is variable then the current at f = 0 and f = ∞ will be respectively :-
Options
A.0A, 8A
B.8A, 0A
C.8A, 8A
D.0A, 0A
Solution
∵ Z = 
At f = 0 Z = ∞ so I = 0
and at f = ∞ Z = ∞ so I = 0
At f = 0 Z = ∞ so I = 0
and at f = ∞ Z = ∞ so I = 0
