The instantaneous value of current in a ac.circuit is I=2sin (100pie t + pie/3)A. The current will be maximum for the first time at a) 1/100sec b)1/600sec c) 1/200 sec

The instantaneous value of current in a ac.circuit is I=2sin (100pie t

1.	The instantaneous value of current in a ac.circuit is I=2sin (100pie t + pie/3)A. The current will be maximum for the first time at a) 1/100sec b)1/600sec c) 1/200 sec
Answer» From the given equation of sine function the current will be maximum when 100piet+pie/3=pie/2 as sin (pie/2)=1 is the maximum value of sign function. So t= 1/100(1/2-1/3)=1/600 sec Hence option (b) is correct
