Use Lagrange multipliers to find the maximum and minimum values of the function subject to the constraints
High-Voltage DC
A system used for the transmission of electrical power over long distances with high voltage in direct current form, reducing power losses and increasing transmission efficiency.
Negative Charge
An electrical charge characterized by the presence of more electrons than protons, resulting in a net decrease in electrical potential.
Precipitator
An environmental control device, such as an electrostatic precipitator, that removes particles from a flowing gas using the force of an induced electrostatic charge.
Air Filter
A device that removes particles, such as dust and pollen, from air to improve quality or protect machinery by preventing the accumulation of contaminants.
