Q1.
a)
b)
A 200V DC series motor has armature resistance of 0.1 Q and field
resistance of 0.15 Q. The motor runs at a speed of 600 rev/min when the
shaft torque is 28 Nm. Friction and windage losses at this speed are 251.3
W. Calculate armature current, copper loss and efficiency.
A DC shunt motor has an armature resistance of 0.22, a field resistance
of 200 and is connected to a 200 V supply.
i) Draw the equivalent electrical circuit of the motor
ii) If the motor runs at 1500 rpm and takes a current of 11 A from the
supply, calculate the output torque of the motor
iii) If the supply voltage is kept constant but the load torque is changed
so that the supply current decreased to 6 A, determine the motor
speed and the output torque.
Three concentric spherical shells 7=1, 7=2, 7=3 m, respectively, have
charge distriutions 2, 4 and 5 µC/m².
(a) Calculate the flux through 7=1.5m and r = 2.5 m.
(b) Find D at 7=0.5m, r=2.5m, and 7= 3.5m.
im not sure this answer makes sense to me.
The question is "Between which terminal block and screw numbers is relay coil CR-7 located?"
The answer points towards lines in a seperate text?
My answer was "TB-5B between screw numbers 2 & 10" could someone please review this and let me know if I am correct?
(This is not for a graded assignment, It is not worth any marks and my professor has not released any answer keys)
