一、各种电路故障分析1.电路短路第一,电源短路.即用导线直接或者间接地将电源两端相连接,而中间未通过任一用电器.若在复杂电路中,有条路能够直接由电源正极走向电源负极,而中间却没有通过任一用电器,则认为是电源短路,其原因在于电流总是从没有阻碍的地方流过去.第二,用电器短路.即串联的用电器中一个或者若干个(并非全部)于电路中不工作,这一现象则视为用电器短路,其原因可能是接线原因,亦或电路出现故障.这一情况通常损坏不大.这一短路现象,也称为局部短路.2.电路断路电路断路是电路故障中的另一情形,也称为开路,即整个电路于某处断开.其原因有:灯丝断了;导线未接好;未闭
First, a variety of circuit failure analysis First, short circuit First, the power supply short circuit, that is, directly or indirectly with the wire to connect the two ends of the power supply, but not through the middle of any electrical appliances If the complex circuit, Directly from the positive power supply to the negative power supply, but not through the middle of any electrical appliances, then that is the power supply short circuit, the reason is that the current always flow from the place where there is no obstruction. Second, the short circuit with electrical appliances that is connected in series One or more, but not all, of the circuits in the circuit does not work, this phenomenon is considered as electrical short circuit, the reason may be due to wiring or circuit failure, which is usually not damaged .This short circuit phenomenon , Also known as partial short circuit .2. Circuit Break Circuit Break is another case of circuit failure, also known as open circuit, that is, the entire circuit somewhere off. The reasons are: the filament is broken; wire is not connected; not close
