Element B in the diagram in Fig. P1.25 supplies 72 W of power. Calculate VA. 3A Figure P1.25 + VAB

For an electrical component, the formulas for charge and voltage are given below. A is 9 coulombs, B is 12 seconds, C is 3 volts, and D is 24 seconds. Give the power of this component at t = 7 sec. You must round your answer to the nearest thousandth and give your answer as an integer followed by the appropriate metric prefix and the letter that represents the units of power.
