1. Impamvu zituma insinga n'insinga zisaza: kwangirika kw'inyuma. Dukurikije isesengura ry'imikorere mu myaka ya vuba aha, amakosa menshi y'insinga aterwa no kwangirika kwa mashini. Urugero: gushyiraho insinga n'insinga si ubwubatswe busanzwe, byoroshye kwangiza mashini; Biroroshye kandi kwangiza insinga n'insinga mu gihe cy'ubwubatsi bw'icyuma ku nsinga n'insinga zihishe mu buryo butaziguye. Hari igihe, niba kwangirika atari gukomeye, bizatwara amezi menshi cyangwa imyaka myinshi kugira ngo igice cyangiritse gisenyuke burundu maze gikore ikosa. Hari igihe kwangirika kuba gukomeye kandi ikosa rya "short-circuit" rishobora kubaho, rikagira ingaruka ku mutekano w'imashini y'amashanyarazi.
2. Impamvu zituma insinga n'insinga zisaza: ubushyuhe butose. Bikunze kugaragara cyane kandi biba ku mpera z'insinga n'insinga zipfundikiye cyangwa mu muyoboro w'amazi. Urugero: imiyoboro y'insinga idakwiye kandi mu bihe by'ubushyuhe kugira ngo ikore iyi miyoboro, izakora iyi miyoboro y'amazi cyangwa ivanze n'umwuka w'amazi, igihe kirekire munsi y'imbaraga z'amashanyarazi kugira ngo ikore amashami y'amazi, byangiza buhoro buhoro imbaraga z'ubushyuhe bw'insinga ziterwa n'ikosa.
3. Impamvu zituma insinga n'insinga zisaza: kwangirika kw'imiti. Iyo insinga zitwikiriwe neza muri ako gace hamwe n'ingaruka za aside na alkali, urwego rw'uburinzi rw'imiti rufite icyuma, icyuma cy'uburinzi cyangwa urwego rwo hanze rw'insinga akenshi ruzangirika. Urwego rw'uburinzi ruzangirika kubera kwangirika kw'imiti cyangwa kwangirika kw'amashanyarazi igihe kirekire, bigatuma urwego rw'uburinzi runanirwa kandi hagagabanuka ubushyuhe, ibyo bikaba byanatuma insinga n'insinga zinanirwa. Kwangirika kw'insinga mu bikoresho bya shimi ni bibi cyane.
4. Impamvu zituma insinga n'insinga bisaza: gukora cyane igihe kirekire. Mu gihe cy'ubushyuhe bwinshi, bitewe n'ingaruka z'ubushyuhe bw'umuyoboro w'amashanyarazi, icyuma gishyuha nta kabuza iyo umuyoboro w'amashanyarazi unyuze mu nsinga. Hagati aho, ingaruka z'uruhu rw'umuriro, gutakaza umuyoboro w'icyuma uturutse ku muriro w'amashanyarazi ndetse n'igihombo cy'ubushyuhe bw'amashanyarazi nabyo bizongera ubushyuhe, bizongera ubushyuhe bw'insinga n'insinga. Mu gihe cy'ubushyuhe bwinshi, ubushyuhe bwinshi buzihutisha gusaza kw'insinga ndetse n'insinga zizangirika. Cyane cyane mu mpeshyi y'ubushyuhe, kwiyongera k'ubushyuhe bw'insinga akenshi bituma insinga zidakora neza, bityo mu mpeshyi, amakosa y'insinga aba menshi cyane.
5. Impamvu zituma insinga n'insinga bisaza: kwangirika kw'insinga. Insinga ni yo ifite intege nke mu murongo w'insinga. Ikosa ry'insinga riterwa n'ikosa ry'abakozi (imiterere mibi) rikunze kubaho. Mu gihe cyo gukora insinga n'insinga, iyo insinga idakandagiwe cyane kandi ubushyuhe budahagije, umuyoboro w'umwimerere uzatuma insinga z'umutwe w'insinga zigabanuka, bityo bigatera impanuka.
6. Impamvu zituma insinga n'insinga zisaza: ibidukikije n'ubushyuhe. Ibidukikije byo hanze n'aho insinga iherereye nabyo bitera ubushyuhe bw'insinga kuba bwinshi cyane, ubushyuhe bugasenyuka, ndetse no guturika n'inkongi.
