List-I (Instrument) List-II (Error)
(w) PMMC voltmeter (i) Eddy current error
(x) AC ammeter ii) Phase angle error
(y) Current transformer iii) Braking system error
(z) EnΓ©rgy mΔter iv) Temperature error
Choose the correct option
(w) PMMC voltmeter β sensitive to temperature variations because the copper coil resistance changes.
β
(iv) Temperature error
(x) AC ammeter (moving iron / dynamometer type) β has errors due to inductance of the coil, which causes a phase shift between current and flux.
β
(ii) Phase angle error
(y) Current transformer (CT) β introduces phase angle error and ratio error, but the most standard classification here is phase angle error.
β
(ii) Phase angle error (βοΈ check if duplication allowed β usually CT = phase angle error)
(z) Energy meter β uses an eddy-current-based braking system; errors arise due to this.
β
(iii) Braking system error

I. The overall reliability of the closed-loop systems is more than that of open-loop system.
II. The transient response in the closed-loop system decays more quickly than in open loop system.
III. In an open-loop system, closing of the loop increases the overall gain of the system.
IV. In the closed-loop system, the effect of variation of component parameters on its performance is reduced.
Of these statements:
I. The overall reliability of the closed-loop systems is more than that of open-loop system.
β False β Open-loop is structurally simpler and often more reliable (fewer components). Closed-loop is more accurate but less reliable due to complexity.
II. The transient response in the closed-loop system decays more quickly than in open-loop system.
β
True β Negative feedback improves damping, reduces overshoot, and speeds up settling.
III. In an open-loop system, closing of the loop increases the overall gain of the system.
β False β Negative feedback actually reduces the overall gain, but improves accuracy and stability.
IV. In the closed-loop system, the effect of variation of component parameters on its performance is reduced.
β
True β One of the main advantages of negative feedback.
