How much power is delivered by a voltage of 13.8 volts DC and a current of 10 amperes?

• A. 130 watts
• B. 138 watts
• C. 140 watts
• D. 150 watts

Answer: (B)

To determine the power delivered by a voltage of 13.8 volts DC and a current of 10 amperes, you can use the power formula from electrical theory, which states that power (in watts) is equal to voltage (in volts) multiplied by current (in amperes). Using this formula: Power (P) = Voltage (V) × Current (I) Plugging in the values: P = 13.8 volts × 10 amperes P = 138 watts This calculation shows that the power delivered under these conditions is indeed 138 watts. Understanding this relationship between voltage, current, and power is fundamental in electrical systems, including those used in ham radio operations.
