The admittance parameter Y12 in the 2 port network in the figure
-
A 20 Ω resistor, a 1H inductor and 1μF capacitor are connected in parallel the combination is driven by a unit step current. Under the steady state, source current flows through
-
A series resonant circuit has parameters 10 ω, 1 H and 0.1 F. It is excited by a voltage v = 100 sin ωt. At resonant frequency, the power dissipated in the circuit is
-
Assertion (A): A tree of graph contains all the nodes of the graph.
Reason (R): The number of links is always less than the number of tree branches.
-
Cells are connected in series to increase
-
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.
