What is the effect of increasing voltage on current if resistance remains constant?

Increasing voltage while keeping resistance constant results in an increase in current. This relationship is defined by Ohm's Law, which states that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R). The formula is expressed as I = V/R.

When voltage rises and resistance stays fixed, the numerator in the equation increases, leading to a higher current output. Each increase in voltage directly contributes to an increase in current, illustrating the fundamental principle that the power supply strength affects the flow of electric charge through a circuit. This understanding is key in electrical theory and practice, as it demonstrates how adjusting voltage levels can effectively control current in various applications.
