Florida Medicine Vascular resistance Physics Electrical resistance, the measure of the degree to which a conductor opposes the flow of an electric current through that conductor Friction Drag (physics) ("air resistance"), fluid or gas forces opposing motion and flow The inverse of Hydraulic conductivity, the ease with which water can flow through pore spaces or fractures in soil or rock Thermal resistance, a measure of difficulty of heat flow through a substance Thermal conductivity, how well heat flows through a substance Thermal resistance in electronics, heat considerations in electronics design Music Resistance to airflow through a wind instrument due to air friction (for instance, a tightly-coiled French horn has higher resistance than a straight unvalved slide trumpet) Topics referred to by the same term
