resistor
含义: An electronic component that limits or regulates the flow of electrical current in a circuit. Its resistance is measured in ohms.
Resistors are among the most fundamental and numerous components in electronics. They control current flow, divide voltages, and protect sensitive components from excessive current. Resistance values are indicated by coloured bands painted on the component — a colour code that electronics students learn early. Variable resistors (potentiometers) allow resistance to be adjusted, and are found in volume controls and dimmer switches.

起源与历史
From 'resist' (from Latin resistere, 'to stand back, withstand,' from re- 'against' and sistere 'to stand') plus the agent suffix '-or.' The electronic component was named in the early 20th century.
