Identify Quadratic Equation: Identify the quadratic equation that models the power generated by the electrical circuit.The given equation is P(x)=−12x2+120x. This is a quadratic equation in the form of ax2+bx+c, where a=−12, b=120, and c=0 (since it is not given).
Determine Vertex Coordinate: Determine the x-coordinate of the vertex of the parabola, which will give us the current that produces the maximum power.The x-coordinate of the vertex of a parabola given by ax2+bx+c is found using the formula x=−2ab. In this case, a=−12 and b=120.
Calculate x-coordinate of Vertex : Calculate the x-coordinate of the vertex using the values of a and b.x=(2⋅−12)−120x=−24−120x=5
Interpret Maximum Power: Interpret the result.The current that produces the maximum power is 5 amperes. This is the x-coordinate of the vertex of the parabola, which represents the maximum point on the graph of the quadratic equation.
