What Is the Relationship Between Voltage, Current, and Power in DC Systems?
Voltage, current, and power are fundamental electrical parameters in direct current (DC) systems. Voltage is the electric potential difference that drives current through a circuit. Current is the flow of electric charge, while power is the rate at which electrical energy is transferred by an electric circuit. The relationship between these three elements can be described by the formula: Power (P) = Voltage (V) × Current (I).
The National Institute of Standards and Technology (NIST) defines voltage as the electric potential difference between two points in an electric field. Current is measured in amperes (A) and represents the flow of electric charge. Power, measured in watts (W), indicates how much energy is consumed or produced in a circuit.
In DC systems, voltage provides the necessary push for current to flow through a load. When voltage increases, current increases, provided that the resistance remains constant. Conversely, if the resistance increases, the current will decrease for a constant voltage. Thus, the relationship is interdependent and governed by Ohm’s Law.
According to the International Electrotechnical Commission (IEC), power can also be influenced by resistance, which affects the overall efficiency of the system. High resistance results in power loss in the form of heat, leading to less energy being delivered to the load.
Voltage and current can vary due to several factors, including circuit components, load demand, and heat dissipation. Fluctuations in these variables can lead to energy inefficiency or system failures.
The U.S. Energy Information Administration (EIA) reports that the electricity generation sector generated approximately 4 trillion kilowatt-hours (kWh) of electricity in the U.S. in 2020. It projects renewable energy sources will account for nearly 50% of electricity generation by 2050.
