Q1.A dual trace oscilloscope is set to operate in the Alternate mode. The control input of the multiplexer used in the y-circuit is fed with a signal having a frequency equal to
Answer : Option CExplaination / Solution: No Explaination.
Q4.The voltage applied to a circuit is volts and the circuit draws
a current of amperes. Taking the voltage as the
reference phasor, the phasor representation of the current in amperes is
The steady state error of a unity feedback linear system for a unit step input is 0.1. The steady state error of the same system, for a pulse input r(t) having a magnitude of 10 and a duration of one second, as shown in the figure is
Q8.A lossy capacitor Cx, rated for operation at 5 kV, 50 Hz is represented by an
equivalent circuit with an ideal capacitor Cp in parallel with a resistor Rp. The
value Cp is found to be 0.102 µF and the value of Rp = 1.25 MΩ . Then the power
loss and tan ∂ of the lossy capacitor operating at the rated voltage, respectively,
Answer : Option CExplaination / Solution: No Explaination.
Q9.Let the Laplace transform of a function F(t) which exists for t > 0 be F1(s) and
the Laplace transform of its delayed version be the
complex conjugate of F1(s) with the Laplace variable set as s=σ + jw. If G(s) = , then the inverse Laplace transform of G(s) is
Q10.A capacitor is made with a polymeric dielectric having an εr of 2.26 and a
dielectric breakdown strength of 50kV/cm. The permittivity of free space is
8.85pF/m. If the rectangular plates of the capacitor have a width of 20cm and a
length of 40cm, then the maximum electric charge in the capacitor is
