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

To find the electrical power delivered in a DC circuit, you use the power formula P = I x E (Power equals Current multiplied by Voltage). This straightforward multiplication calculates the total wattage. In this scenario, you are given a voltage (E) of 13.8 volts and a current (I) of 10 amperes. Plugging these values into the formula yields P = 10 A x 13.8 V, which calculates to exactly 138 watts. The distractors are simply the results of incorrect math operations. Adding the numbers gives 23.8, subtracting them gives 3.8, and dividing them results in 0.7 or 1.38, none of which correctly calculate power.
