What happens to current flow when voltage increases?

When voltage increases, the flow of current increases as well, provided that the resistance in the circuit remains constant. This relationship is described by Ohm's Law, which is formulated as V = I × R, where V represents voltage, I represents current, and R represents resistance. According to this principle, if the voltage (V) in a circuit is increased while the resistance (R) does not change, the current (I) must increase to maintain the equality of the equation.

It's also important to note that while this relationship holds true for resistive loads in Ohmic conductors, other types of circuits, such as those involving inductance or capacitance, may exhibit different responses to voltage changes due to reactance. However, in a simple resistive circuit, increasing the voltage leads directly to an increase in current flow. This understanding is fundamental in electrical and HVAC systems to ensure proper function and safety.
