| 41. | The terms RMS and average values apply only to sine waves. |
|||
Answer: Option B Explanation: These terms are applicable to all waveshapes. |
| 42. | For a transmission line open circuit and short circuit impedances are 20 Ω and 5 Ω. Then characteristic impedance is |
|||||||
Answer: Option D Explanation: Z0 = √Zoc Zsc . |
and i(t) is a unit step, then V(t) in the steady state is given by
| 44. | The driving-point impedance Z(s) of a network has a pole-zero locations as shown in the figure. If Z(0) = 3, then Z (s) is |
|||||||
Answer: Option B Explanation: |
while in question Z(0) = 3 
| 45. | When a current source I is suddenly connected across a two terminal relaxed RC circuit at time t = 0, the voltage across the current source is shown in figure. The RC circuit is |
|||||||
Answer: Option C Explanation: Initially capacitor behaves as short-circuit and finally as open circuit. |
| 46. | In a minimum function |
|||||||
Answer: Option A Explanation: If degrees of numerator and denominator were unequal, a pole or zero can be removed. Such a function cannot be a minimum function. Therefore degrees of numerator and denominator must be equal. |
| 47. | Henry is equivalent to |
|||||||
Answer: Option C Explanation: Inductance is flux per ampere. |
| 48. | An RLC series circuit is underdamped. To make it overdamped, the value of R |
|||||||
Answer: Option A Explanation: For overdamping R is more. |
