Figure shows a parallel resonant circuit having resonance frequency of 15 MHZ. At this frequency
-
In an R-C circuit, there is an initial voltage of 3 V across the capacitor. In s domain equivalent circuit, the voltage source to take into account the initial voltage has a strength of
-
An electrical network with 8 independent nodes will have __________ nodal equations.
-
An RLC series circuit has . If the poles p1 and p1* are close to jω axis, then
-
Assertion (A): When a square periodic wave is applied to an RC circuit, the voltage across capacitor is observed to be a triangular periodic wave.
Reason (R): The RC circuit works as integrator and its time constant is much larger than time period of input wave.
-
Assertion (A): In a series resonant circuit current is maximum at resonance.
Reason (R): The inductive and capacitive reactances are equal.
-
A series RL circuit is excited by a voltage v(t) = Ve-at such that a = R/L. Then the circuit current is
-
In the transformer shown in the figure, the inductance measured across the terminal 1 and 2 was 4 H with open terminals 3 and 4. It was 3H when the terminals 3 and 4 were short circuited. The coefficient of coupling would be
-
An ac network has two sources of the same frequency. The currents in one branch when the sources act independently are 10 ∠30° A and 10 ∠60° A. When both sources act, the current in the branch should be
