$\"\"$

\

The current function is $\"\"$ .

\

Where $\"\"$ is the current in amperes and $\"\"$ is the time in seconds.

\

The general form of sine function is $\"\"$ .

\

Where, $\"\"$ is amplitude and period is $\"\"$ and phaseshift is $\"\"$ .

\

Compare the function with general form of sine function.

\

$\"\"$ , $\"\"$ and $\"\"$ .

\

Here amplitude is $\"\"$ .

\

The period is $\"\"$ .

\

$\"\"$

\

$\"\"$ .

\

Phaseshift is $\"\"$ .

\

$\"\"$

\

Therefore, the amplitude is $\"\"$ and time period is $\"\"$ and phaseshift is $\"\"$ .
