The factors that affect the flow of electric charge will be Voltage and resistance.
The flow of the charge depends upon the voltage because the voltage is responsible to push or it applies the force on the particles to flow.
For example, whenever your battery gets discharged what happens is the potential difference of voltage becomes zero.
So there will not be enough force remaining in the battery to flow the charge but when we charge the battery then it regains its voltage and again pushes the charges to flow.
Now the resistance acts just opposite to the voltage because it restricts the flow of the charges so if the resistance is more then more voltage is required to flow the charge.
Thus the factors that affect the flow of electric charge will be Voltage and resistance.
