12 V is the f.e.m. 
of the battery. The potential difference that is applied to the motor is actually the fem minus the voltage drop on the internal resistance r:
this is equal to the voltage drop on the resistance of the motor R:
so we can write:
and using
and 
we can find the current I:
this is equal to the voltage drop on the resistance of the motor R:
so we can write:
and using
Answer:
Explanation:
Given
n=5
0.3 fraction recrystallize after 100 min
According to Avrami equation
where y=fraction Transformed
k=constant
t=time
Taking log both sides
At this Point we want to compute
taking log both sides
Rate of Re crystallization at this temperature
