In a circuit, adding more resistance will do what to the current flow?

Adding more resistance to a circuit decreases the current flow. This relationship is defined by Ohm's Law, which states that current is equal to voltage divided by resistance (I = V/R). When resistance increases while the voltage remains constant, the overall current in the circuit will decrease. This principle is fundamental in electrical engineering and is vital for understanding how resistive components interact within a circuit.

For instance, in a practical scenario, if you were to add a resistor in series with other components in the circuit, the overall resistance increases, which directly leads to a lower current according to Ohm's Law. This is crucial for circuit design and troubleshooting, as engineers often need to calculate current changes based on alterations in resistance.
