# Relationship of Voltage, Current, and Resistance

The relationship between voltage (V), current (I), and resistance (R) is governed by Ohm’s Law, which states that V = I * R. This equation shows that voltage across a component is directly proportional to the current flowing through it, given a constant resistance. If the resistance remains unchanged, increasing the voltage will result in a corresponding increase in current, and vice versa. This relationship is fundamental in understanding how electrical circuits behave and is applicable across various devices and systems.

Voltage and resistance are inversely proportional to current according to Ohm’s Law. This means that if resistance in a circuit increases, for a given voltage, the current decreases, and vice versa. Conversely, if the voltage increases for a given resistance, the current increases. This inverse relationship is crucial in designing and analyzing electrical circuits, where adjusting voltage or resistance affects the current flow accordingly.

The relationship between volts (V), amps (A), and resistance (R) is described by Ohm’s Law, which states V = I * R. This equation shows that voltage (measured in volts) is equal to the current (measured in amperes) multiplied by the resistance (measured in ohms). It illustrates how these quantities interact in electrical circuits: increasing voltage or reducing resistance will increase current, and vice versa.

In a series circuit, the relationship between resistance and voltage can be understood through the voltage divider rule. According to this rule, the total voltage supplied by the source is divided among the resistors in proportion to their individual resistances. This means that in a series circuit, the voltage drop across each resistor is directly proportional to its resistance. Higher resistance components will experience a larger voltage drop compared to lower resistance components, assuming the same current flows through all resistors in series.
