So, If the resistance decreases, then the current increases. Assume voltage is constant.
If the voltage increases, then the current increases. Assume resistance is constant.
Explanation:
According to the ohm's law; I = V/R;
- If the resistance decreases the current increases assuming that the voltage is constant
- if the voltage increases, then the current increases assuming that the resistance is constant.
Based on Ohm's law, we know that the current through a metallic conductor is directly proportional to the voltage across the ends.
From the relationship;
I =
we see that V = IR
These equations affirms that
- If the resistance decreases the current increases assuming that the voltage is constant based on the second equation
- if the voltage increases, then the current increases assuming that the resistance is constant based on the first equation.
