If voltage remains constant and current increases, what happens to resistance?

When voltage remains constant and current increases, resistance decreases according to Ohm's Law, which states that the relationship between voltage (V), current (I), and resistance (R) is given by the formula V = I x R. Rearranging this formula to express resistance gives us R = V / I.

In this formula, if the voltage (V) is held constant and the current (I) increases, the calculation indicates that resistance (R) must decrease to maintain the equality. Consequently, a higher current at a constant voltage leads to a smaller value for resistance. This reflects the fundamental principle of how conductors behave under varying electrical conditions.

Thus, when faced with an increase in current while voltage is constant, it is essential to understand that the resistance must inevitably decrease.
