DC Power Calculator

What is a DC Power Calculator?

A DC Power Calculator is a tool that calculates the electrical power in a direct current (DC) circuit using voltage and current values. It helps in understanding the relationship between these electrical quantities in DC systems.

The Formula

The formula for calculating DC power is:

\[P = V \times I\]

Where:

• P is power in watts (W)
• V is voltage in volts (V)
• I is current in amperes (A)

DC Circuit Diagram

A basic DC circuit consists of a power source (like a battery) and a load (like a resistor):

In this diagram:

• V represents the voltage source (battery)
• R represents the load (resistor)
• I represents the current flowing in the circuit
• The power (P) consumed by the resistor is the product of V and I
