Electric charge passing through a cross section is quadratic function of time then what can be said about electric current?
Electric current is constant
Electric current is also quadratic function of time
Electric current is linear function of time
We cannot determine electric current
As we learnt
Electric current -
- wherein
Instantaneous Current
tends to zero
Since i= dq/dt
Q is quadratic function of time hence on defferentiating we will get current as linear function of time.
Option 1)
Electric current is constant
Option 2)
Electric current is also quadratic function of time
Option 3)
Electric current is linear function of time
Option 4)
We cannot determine electric current
