A system function
, the system is at rest for t < 0. For i(t) = u(t), then v(t) is given by -
Two voltages 50 V each have a phase difference of 45°. The rms value of resultant sum of the two voltages is
-
The energy stored in a coil is 108 J. It is opened suddenly in 10 ms. The power dissipated instantaneously across the blades of switch is
-
A parallel RLC circuit with R1 = 20,
is scaled giving R2 = 104, L2 = 10-4 and C2, the value of C2 is -
The Thevenin's equivalent of network in figure(1) is a 10 V source in series with 2 Ω resistance. If a 3 Ω resistance is connected across AB as shown in figure(2) the Thevenin's equivalent is
