The relationship between current and voltage can be described using Ohm's Law. Ohm's Law expresses the relationship between current, voltage, and resistance with the formula:

Current (I) = Voltage (V) / Resistance (R)

This indicates that current is directly proportional to voltage and inversely proportional to resistance. When voltage increases, if resistance remains constant, current also increases. Conversely, if voltage decreases, current decreases as well.

In addition to Ohm's Law, the relationship between current and voltage is also influenced by circuit components like resistance, inductance, and capacitance. In AC circuits, the phase difference and frequency between current and voltage also affect their relationship. Overall, the relationship between current and voltage depends on the characteristics of the circuit and the properties of the components.
