串联电路

It is called series circuits in physics.

它在物理学上被称为串联电路。

More bulbs in the series circuit will decrease their brightness. A smaller current will flow.

在串联电路中增加灯泡会降低它们的亮度， 而电路中的电流也会减小。

In a series circuit, the electric current at every point is the same.

在串联电路上各点的电流是相等的。

Series circuits have the advantage of increasing resistance to reduce current when this is desirable.

串联电路的优点是能够在需要时加大电阻以减小电流。

They keep the light fixtures insulated with the HV series circuit to avoid electric shock accident.

同时，电路中某些灯泡烧坏时，隔离变压器的初级绕组可以保持串联电路的导通，使其它灯具仍能正常工作。
