In an experiment on studying the dependence of current (i) flowing through a given resistor on the potential difference (v) applied across it, list two ways how a student would change the values of current in the circuit?

According to ohms law I=V/R
So in this relation we can see value of current depends upon potential as well as reaisresis of circuit. So there are twao ways
1. By increasing or decreasing the temperature of surrounding because resistance of circuit depends upon length and as we increase the temperature resistance will also increase and change in resistance can change the value of current.
2. By increasing or decreasing the cross section area of resistor.
