Answer:
 T = 0.017s
Explanation:
period is the time it takes a particle to make one oscillation
 An electric current is periodic in nature
The current reaches 3.8A  ten times.  
So there must have been 10 cycles (10 periods) in 0.17s.   let 'T'  be the period:

t is the total time interval
n is the number of oscillations

10T = 0.17
T = 0.17/10 = 0.017s
