A 120 V shunt motor has armature resistance of 0.1 ohm and field winding resistance of 60 Ohm. The total brush voltage drop is 2 V. The motor operates at the rated load and draws line current of of 32 A at a speed of 200 rad/s. Calculate:
a. Field current and armature current
b. The counter emf Ea
c. The developed power in kW
d. The developed torque in N-m

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
