In the power equation, what value is divided by volts to determine amps?

Watts
Volts
Ohms
Amperes

The correct answer is: Watts

In the power equation, power is defined as the product of voltage and current (measured in watts). To find the current in amps, you can rearrange the power equation, which states that power (in watts) equals voltage (in volts) multiplied by current (in amps). Therefore, to isolate the current, you would divide the power (watts) by the voltage (volts). This means that when you need to calculate the number of amps flowing in a circuit, you take the total power consumed (in watts) and divide it by the voltage (in volts). This relationship is critical in electrical calculations and helps ensure that circuits are designed safely and effectively by preventing overloads and ensuring adequate power supply to devices. Understanding this equation is fundamental in marine electrical practices, where efficient power management is crucial for safety and functionality. Knowing the correct usage of the power equation allows marine technicians to troubleshoot electrical issues accurately and efficiently.
