Answer: If the time interval remains constant, the current will increase when the amount of charge is increased.

Explanation: The current intensity `I` of a charge `Q` that passes through a certain section of a conductor in the time `t` is by DEFINITION

`I = Q/t` .

Therefore the current is directly proportional to the charge and inversely proportional to the flow time. Increasing charge, increases the current if the time remains the same.

Observation:

From the expression above one usually further define the density of current `j` as being the current that flows through the unity surface.

`j = I/S =Q/(t*S)`
