20 x 400 8000 8kΩ.
12.
A series RLC circuit has a resonance frequency of 1 kHz and a quality factor Q = 100. If each of R, L and C is doubled from its original value, the new Q of the circuit is
Answer: Option
Explanation:
, If R, C are doubled then 
.
13.
Assertion (A): The polynomial s3 + 6s2 + 12s + 8 is Hurwitz.
Reason (R): In a Hurwitz polynomial all coefficients are non-negative.
14.
A dc network has an open circuit voltage of 5 V. When its terminals are short circuited a current of 5 A flows through the short circuit. If the short circuit is removed and a resistance of 1.5 Ω is connected across its terminals, the current will be
Answer: Option
Explanation:
15.
A coil of resistance R and inductance L has a capacitor C in parallel with it. The source frequency is adjusted to a value equal to resonant frequency. Another capacitor C is added in parallel with the above circuit, the source current will
Answer: Option
Explanation:
The circuit will not in resonance. In parallel resonant circuit the current is minimum at resonance. Therefore, current will increase.
