Answer:
The current in the motor in this case is 13.2 A
Explanation:
Given:
Resistance 
5 Ω
Emf 
V
Induced emf 
V
When motor run at half speed due to load increased then induced emf is also reduced to half of its value
So new induced emf in our case is given by,
V
Where 
A
Therefore, the current in the motor in this case is 13.2 A
