A tool that facilitates the determination of power in kilowatts (kW) from a given current in amperes (amps). This calculation requires additional information such as voltage and, in the case of alternating current (AC), the power factor. For example, a direct current (DC) circuit with 10 amps at 120 volts equates to 1.2 kW; this is derived by multiplying amps and volts, then dividing by 1000.
Understanding electrical power relationships is crucial for electrical system design, load management, and safety. This type of calculation assists in selecting appropriately sized equipment, preventing overloads, and ensuring efficient energy consumption. Previously, these computations were performed manually, but automated versions have simplified the process and reduced the potential for error.
