Question

Problem-An alternating current is given by \(i=141.4\,sin\,(314t)\)

Find

i) The maximum value 

ii) Frequency 

iii) Time Period 

iv) The instantaneous value when t = 3ms, i =141.4 sin(314t)

Answer 1

\(i=i_{m}sin\,(\omega t)\)  ..........(1)

Compare given equation with eq-1,

Maximum value \(i_{m}=141.4volts\)
