　　Water to low water flow，Current to low potential flow。

　　Circuit，Similar to the water pump is the power supply：Voltage source or current source。

　　Water pump pump water from low water level to high water level，Power supply to flow from low 巴慕达加湿器售后服务 potential to high potential。

　　Car walking road，Train road called railway。Everyone knows to make the current work，It must be called it to flow according to the specified route，We call the route of the current is called circuit.。Circuit and railway、Highway，railway、Highways 巴慕达净化器维修 can extend and shortened，There is also a tail，And the circuit is a closed loop.。such，Current can only flow in closed circuit。Circuit is generator generating electric energy（battery）And use electrical appliances，Motor、Electric light, etc.，Electrical auxiliary equipment，Switch、Instrumentation。Want to make the current pass the circuit，Established electrical switch in the circuit；To stop the current stop，As long as the electrical switch in the circuit can be opened。This is as we have to cross the river.，First of all, you can get a bridge.，I can't go in the bridge.。
