If an arc is represented by `I=100sin200pit` ampere, determine the peak value of current and time period.

Text Solution

Verified by Experts

Comparing with the general equation of ac, `I=I_0sin(omegat+alpha)` we get,
the peak value of current `I_0=10A`
and angular frequency , `omega=200piHz`
`therefore` Time period, `T=(2pi)/omega=(2pi)/(200pi)=0.01s`
