Question : 195 of 200

Marks: +1, -0

i(t) = 50 \cos (100\πt + 10°)

is the expression of a sinusoidal current, find the maximum amplitude.

Solution:

Sinusoidal wave is given as,

i(t) = 50 \cos (100\πt + 10°)

Comparing to the given equation

i = \I _{ \m } \sin (2 \π \ft +\ϕ)

∴\I _{ \m }= 5 0 \A
