How does increasing resistance affect current when voltage stays constant?

According to Ohm’s law, the relationship between current (I), voltage (V), and resistance (R) is expressed by the equation I=V/R.

When the voltage remains constant, the current is inversely proportional to the resistance. Therefore, if you increase the resistance in a circuit, the current will decrease. Conversely, if you remove resistance, the current will increase. This occurs because resistance acts as an opposition to the flow of electric current, transforming electric energy into heat as charged particles collide with the structure of the conductor.12
