Which one of the following measurement CANNOT be done with multimeter?
(ಗೆ) Current drawn by an electronic circuit
(B) Supply voltage to DC motor
(C) Continuity test of motor winding
(D) TInsulation resistance of motor

Why a higher capacity squirrel cage induction motor is not recommended for operating under
low load condition? :

(வ) Vaoltage drop in line will be too much

(B) Power factor will be less

(C) Higher capacity mofors does not run at constant speed
(D) Torque is too much hence it may cause damage

Shunts and multipliers used in MC instruments are made up of Mangnin. The reason for
using the above metal is that, it has:

(^) Positive temperature co-efficient of resistance

(ए) Negative temperature co-efficient of resistance

(ര Perfectly constant temperature co-efficient of resistance

(D) Very low (practically constant) temperature co-efficient of resistance

In order to operate a fluorescent tube set on DC supply, which of the following additional
auxiliary device is to be connected?

(^) Inductance (8) Capacitance

(0 Resistance (D) No extra device is needed

The power input increases by three times when the connection of three phase loads changes
from star to delta at the same line voltage. What is the reason for this?

(A) The voltage across one phase of the load is three times higher in delta connection
than in star connection

(B) The power factor increases by three times in delta connection when compared to
star connection

(0 The line current is three times higher in delta connection than in star connection

(D)) _The voltage in each phase increases by two times and the current by 1.732 times

In a parallel resonant circuit the capacitor current is ‏٭‎
‎(ക) More than line current (B) Less than line current
(0) Equal to line current (D) None of the above

According to National electric code what is the specified minimum distance between the
washing unit and the switch board :

(ಗಿ) 0.6 metre (B) 1.3 metre

(C) 2.5 metre (D) 3.4 metre
