When voltage increases, what is the expected effect on current flow?

When voltage increases in an electrical circuit, the expected effect on current flow is that it increases. This relationship is defined by Ohm's Law, which states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points, assuming the resistance (R) remains constant. Mathematically, this is expressed as I = V/R.

As the voltage rises, if the resistance of the circuit does not change, the current that flows through the circuit will also increase. This principle is fundamental to understanding how electrical systems work and is applicable in various practical scenarios within salon equipment, such as hair dryers, where adjusting the voltage can impact performance and efficiency.
