If the frequency of the ac circuit illustrated ... - WAEC Physics 1990 Question
If the frequency of the ac. circuit illustrated above is 500/π Hz what would be the reactance in the circuit?
A
0.0009Ω/π
B
100Ω
C
1030Ω
D
1400Ω
correct option: d
= 2ufl - 1/2ufc = (2 x (500/π) x 0.9) -
1/2 x (500/π) x 2 x 0-6 = 1440Ω
