Question

What determines the flow of charge?

Answer 1

The flow of charges inside any conductor or conducting material is called the current.

The formula for the current is,

$I=\frac{V}{R}$

Here, V is the voltage and R is the resistance.

The equation for the current shows that the current is dependent on the resistance and the voltage.

The current has an inverse relationship with the resistance and proportional relation with the voltage.

Thus, the flow of charge is defined by voltage and resistance.
