As resistance decreases, current increases if the power supply is constant

As the resistance in a circuit decreases, the current in the circuit increases, as long as the power supply remains constant. This happens as resistance is the opposition to current, so the lower the resistance, the less current is restricted, therefore it increases.

Here is an example of this in action in a real scenario:

Previous
If resistance doubles, current halves if the power supply is constant
Next
If resistance halves, current doubles if the power supply is constant
