What is the effect of increasing resistance in a circuit?

Increasing resistance in a circuit has a direct effect on the current flow according to Ohm’s Law, which states that current (I) is equal to voltage (V) divided by resistance (R): I = V/R. When the resistance in a circuit increases, the denominator in this equation becomes larger, leading to a decrease in the overall current flowing through the circuit, assuming the voltage remains constant. This relationship explains why higher resistance results in lower current flow.

Moreover, in practical applications, this principle is essential for designing circuits and ensuring they operate within safe limits. Increased resistance could also lead to the generation of heat in the components, which is another consideration in electrical engineering. Therefore, the understanding of how resistance affects current flow is vital for anyone working with electrical systems.
