Assertion (A): The s domain impedance of a series R-L circuit is R + sL irrespective of initial conditions.
Reason (R): Complex frequency s = σ + jω.
Answer: Option
Explanation:
The s domain equivalent depends on initial conditions.
42.
If Va = 10 ∠0, Vb = 10 ∠ -120° and Vc = 10 ∠ -240°, then Va2 and Va0 are
Answer: Option
Explanation:
Since it is a balanced system of voltages, Va2 and Va0 must be zero.
43.
A wire has a diameter d and resistance R. If the diameter is made 3d, the length and material remaining the same, the new value of resistance will be
Answer: Option
Explanation:
Since diameter is 3d, area of cross-section is increased 9 times. Therefore, resistance is R/9.
44.
The realization of a reactance function gives
Answer: Option
Explanation:
Both XL and XC are reactances.
45.
The correct relation between energy and charge is
Answer: Option
Explanation:
Energy = V x I x t since I x t = Q, energy = voltage x charge.
