<prompt> Yakha inguqulo eyinkimbinkimbi yalesi sigwebo eyaziwa nangokuthi i-let-through voltage.  <response>: Yiqiniso, inguqulo eyinkimbinkimbi yomusho ithi Eyaziwa nangokuthi i - let - through voltage, lokhu kucacisa ukuthi yiliphi i - spike voltage elizokwenza izingxenye ezivikelayo ngaphakathi kwesivikeli se - surge ziphambukise amandla angafuneki kulayini ovikelwe.
