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
At f = 0 XC = ∞ and Z = ∞
and At f = ∞ XL = ∞ and Z = 0
so I = 0
and At f = ∞ XL = ∞ and Z = 0
so I = 0
