The relationship of power, current and voltage.

The power dissipated in a closed circuit is equal to the current in the circuit multiplied by the voltage applied to the circuit.

The online calculator below allows you to find:
- Power through current and voltage;
- Voltage through power and current;
- Current through power and voltage.

Current power and voltage are the main parameters in electrical circuits and have a direct relationship with each other. Current power determines the rate at which energy is transferred through a circuit, while voltage determines the force at which energy is transferred through a circuit.

The power of the current is calculated as the product of the current flowing through the conductor and the voltage applied to its ends. Mathematically, this is expressed by the formula P = I * V, where P is the current power, I is the current flowing through the conductor, V is the voltage applied to its ends.

The relationship between current power and voltage can be explained using the example of an electric lamp. If voltage is applied to the lamp, then current will flow through it, and it will begin to glow. The higher the voltage, the more current flows through the lamp, and the brighter it glows. However, this also increases the power consumption of the lamp.

It should be noted that current power and voltage are interrelated, and changing one of them can lead to a change in the other. For example, if you increase the voltage applied to the circuit, then the power of the current passing through it will also increase. Conversely, if you decrease the voltage, then the current will also decrease.

It should also be noted that current power can be lost as heat, especially when high resistance conductors are used. In such cases, some of the energy transmitted through the circuit is converted into heat, which can lead to overheating of the conductors and other problems.

In conclusion, current power and voltage are the main parameters in electrical circuits and have a direct relationship with each other. Current power determines the rate at which energy is transferred through a circuit, while voltage determines the force at which energy is transferred through a circuit. When using electrical circuits, the power of current and voltage must be considered to avoid overheating and other problems associated with the loss of power in the form of heat.
