Antihypotensive agent. An antihypotensive agent, also known as a vasopressor agent or pressor, is any medication that tends to raise reduced blood pressure.
A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor. All other factors being equal, in a direct-current (DC) circuit, the current through a resistor is inversely proportional to its resistance, and directly proportional to the voltage across it. This is the well-known Ohm's Law.
