An inductor in an electric circuit is essentially a coil of wire in which the voltage is affected by a changing current. Bydefinition, the voltage caused by the changing current is given by VL=L(di/dt), where L is the inductance (in H). If VL=9.0−0.4t for a 3.0-H inductor, find the current in the circuit after 20 s if the initial current was zero.

After 20 s, the current is A.

The table represents a function f(x). what is f(3)? a.-9 b.-1 c.1 d.9
