Question 1

The characteristics of a mode of controller are summarized:
1) If error is zero, the output from the controller is zero.
2) If error is constant in time, the output from the controller is zero.
3) For changing error in time, the output from the controller is |K|% for every 1% sec–1 rate of change of error.
4) For positive rate of change of error, the output is also positive.
The mode of controller is

Question 2

The equivalent resistance between terminals x-y in the resistance network is

Question 3

If two capacitors C1 = 10 μF and C2 = 20 μF are connected in parallel with third capacitor C3= 30 μF in series, then the equivalent capacitance results as:

Question 4

Question 5

Assertion (A) : A d.c. motor draws high current at the time of starting
Reason (R) : While starting a d.c. motor, it takes some time to develop a non-zero value of back e.m.f.
