Assertion (A): A series RLC circuit resonates when excited by variable frequency source.

Reason (R): Resonant frequency is geometric mean of half power frequencies.

1. A μP generally interfaced to several memory chips and I/O devices
2. Address space provided by μP is partitioned into sub sets of addresses
3. Address map and address partition refer to different terms in address space

1. The intersection of root locus branches with the imaginary axis can be determined by the use of Routh criterion
2. Segments of real axis having an odd number of real axis open loop poles plus zeros to their right are not parts of root locus
3. The number of root locus branches terminating on infinity is always zero

1. open K_b
2. close K_g
3. close K_b
4. open K_g

1. Parallel
2. Updown
3. Single slope
4. Dual slope
5. Successive approximation
6. Stair step

Assertion (A): When frequencies of signals fed to X and Y plates of CRO are multiples of each other, Lissajous pattern is displayed on screen.

Reason (R): In a CRO, the vertical deflection is proportional to voltage applied to Y plates.

Match the following:

1. Z₁₂ = Z₂₁
2. Y₁₂ = Y₂₁
3. h₁₂ = h₂₁
4. AD - BC = 1

1. Maximum energy of electrons liberated photoelectrically is independent of light intensity
2. Maximum energy of electrons liberated photoelectrically varies nonlinearly with frequency of incident light.
