The quantity of charge q (in coulombs) that has passed through a surface of area 2.00 cm² varies with time according to the equation q = 4t³ + 5t + 6, where t is in seconds. (a) What is the instantaneous current through the surface at t= 1.00 s? (b) What is the value of the magnitude of the current density at this time?

Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
