Question

a) identify the device. b) After observing the figure write down the parts represented by R1,R2, ABCD b) If the current is flown as shown in the diagram, what will be the direction of rotation of armature? c) What is the function of the split-ring commutator in electric motors?

Answer 1

❖ AnswerS ❖

$\rule{200}2$

a) Electric motor

$\rule{200}2$

b)

R₁ and R₂ are split rings

ABCD is a rectangular coil ( also called armature)

$\rule{200}2$

c)

side AB of coil will move downward.

so, armature will rotate anticlock direction.

$\rule{200}2$

d)

In electric motors split rings like commutator reverses the direction of current in armature coil.
