riz-IS-tur
/ɹɪˈzɪstɚ/
resistor is pronounced riz-IS-tur (/ɹɪˈzɪstɚ/). A noun referring to a passive electrical component that limits current by producing a fixed resistance. It can also describe a person or thing that resists or hinders something. In electronics contexts, it designates a specific, measurable resistance value used in circuits.
A noun referring to a passive electrical component that limits current by producing a fixed resistance. It can also describe a person or thing that resists or hinders something. In electronics contexts, it designates a specific, measurable resistance value used in circuits.
"The resistor in the circuit set the current to a safe level."
"She described him as a political resistor to reform."
"The color bands on the resistor indicated its resistance value."
Pronounced ri- ZIS-tor (US) or ri- ZIS-tər (UK/AU). Primary stress falls on the second syllable: re-SIS-tor. The first vowel is a short, lax /ɪ/ as in “sit,” followed by a crisp /z/; the final syllable /tər/ often reduces to /tɚ/ in American speech. Visualize the tongue high-mid for /ɪ/, apex contacting the alveolar ridge for /z/, and a light, quick /t/ before a relaxed schwa. You can listen to examples in technical dictionaries or Forvo for precise real-world pronunciation.
Two frequent errors: (1) placing stress on the first syllable (RE-si-stor) instead of second (re-SIS-tor); and (2) mispronouncing the final -tor as a hard /oʊr/ or not reducing to a schwa. Correction: keep the secondary syllable clearly stressed, and pronounce the last syllable as /tər/ or /tɚ/ with a short, neutral vowel. Also avoid a prolonged /ɪ/ in the middle; use a short /ɪ/ followed by a crisp /z/. Practicing with minimal pairs like ‘resistor’ vs ‘resist or’ helps reinforce the standard rhythm.
Across US, UK, and AU, the core segments stay similar: ri-SIS-tor, with stress on the middle syllable. US English often reduces the final /ɚ/ or /ər/ heavily, yielding /tɚ/. Non-rhotic UK accents may make the final syllable sound like /tə/ or /tə(r)/ with less rhoticity. In Australian English, you’ll hear a more centralized vowel in the second syllable and a slightly broader /ɜː/ or /ə/ in the final syllable depending on the speaker. Overall, the rhyme and stress are consistent; vowel quality and rhoticity shift subtly by region.
The difficulty often lies in the rapid transition between the second syllable’s /ɪ/ and the /z/ cluster, plus producing a clean final /t/ before a schwa. The sequence re-SIS-tor requires precise timing: avoid a dull, clipped /ˈrɪzɪstɔː/ or an extraneous vowel in the middle. People also misplace emphasis or blur the /t/ into /d/. Focusing on a crisp second syllable nucleus /ɪ/ followed by an unambiguous /z/ and a relaxed final /tɚ/ or /tər/ will help.
There is no silent letter in ‘resistor.’ All letters contribute to the standard pronunciation: /rɪˈzɪstə(r)/ with the typical American /tɚ/ or British /tə/ realization. The letters are spacing-guides rather than indicators of silent sounds. The nearest point of confusion is the subtle vowel reduction at the end in fast speech, but the letter “r” in non-rhotic contexts may be less pronounced.

Resistor comes from the Latin verb resistere, meaning to withstand or oppose, via the noun form resistor. The term entered English through electrical engineering usage in the late 19th to early 20th century as the function of a passive circuit element was formalized. The root resist- derives from Latin resistere (to resist, oppose), with -or denoting an agent noun in English, indicating “one who resists.” Early electrical terminology borrowed many Latin and Greek roots to describe circuit components, with resistor appearing alongside conductors, capacitors, and inductors. The earliest resistive components were metal filaments and carbon compositions used in early telegraph and radio-era circuits. By the 1920s, standardized nomenclature and color-code systems (e.g., color bands for resistance values) cemented “resistor” as the standard term in American and British manuals. Over the decades, the basic concept stayed constant—an element that impedes current—but the forms diversified into carbon film, metal oxide, and surface-mount varieties, each maintaining the same fundamental resistance function while varying in tolerance, temperature coefficient, and packaging. The word’s stability reflects its essential role in controlling electrical flow rather than evolving away from its original semantics. First known usage in technical literature aligns with early electronics’ expansion, circa 1900–1920, where engineers explicitly described devices that impede current as resistors rather than more abstract “resistance devices.”
