The current flowing through an electric circuit is the derivative of the charge as a function of time. if the charge q is given by the equation q(t)=3t^2+2t-5 what is the current at t = 0?

The current at t = 0 is

units of current

Step-by-step explanation:

If the current flowing through an electric circuit is defined as the derivative of the charge as a function of time and we have the equation of the charge as a function of time, then, to find the equation of the current, we derive the equation of the charge.

Simplifying the expression we have:

Finally, the equation that defines the current of this circuit as a function of time is:

Now to find the current at t = 0 we make

units of current

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
