Relation between current in a conductor and time is shown in fig.

Write the expression of current in terms of time.

Options

A. `i=(i_(0)t)/(t_(0))`
B. `i=i_(0)(1+(t)/(t_(0)))`
C. `i=i_(0)((t)/(t_(0))-1)`
D. `i=i_(0)(1-(t)/(t_(0)))`

Answer

4

Explanation

Equation of current will be equivalent to equation of straight line with -ve slope
y=mx+c
`i=-(i_(0))/(t_(0))t+i_(0)`
`therefore i=i_(0)1-(t)/(t_(0))`
