11.
In figure, the steady state current through 1H inductance is
Answer: Option
Explanation:
In steady state inductance behaves as short-circuit.
12.
Impedance Z as shown in the given figure is
Answer: Option
Explanation:
Z = j5 + j2 + j2 + 20j - 20j = 9jΩ.
13.
A resistance R, inductance L and capacitance C are in series. The source frequency is adjusted to be equal to resonant frequency. The lower half power frequency is ω1. Another resistance R is added in series with the circuit. The new lower half power frequency will be
Answer: Option
Explanation:
As R increases, Q decreases, bandwidth = 
. Therefore, bandwidth increases. Hence lower half power frequency will be less than ωr.
14.
The strength of controlled voltage source depends on
Answer: Option
Explanation:
A controlled voltage source may be a voltage source or current source and its strength may depend on another voltage or current.
