Electricity
Circuit 電路
: a complete path that allow electricity to flow
三組成要件
A connector (wires)
the source powers a load (light bulb or motor)
A power source (battery)
二種電位
Open circuit (開路) is a circuit with a gap
Closed circuit (閉路) is an unbroken circuit
二種電路
Parallel circuit (平行電路): electric current flows through more than one path
series circuit (串聯電路) electric current flows in the same direction along a single path
What
Static electricity 靜電
The buildup of negative charges on an object.
Discharge 放電
The movement of negative charges that transfers static electricity from one object to another
電荷
(帶有電的物質)
Positive Charge 正電荷
Like charges repel each other (positive to positive or negative to negative). 同性電荷相斥
Negative charge 負電荷
Opposite charges attract each other (negative to positive). 異性電荷相吸
electric current 電流
a flow of electricity through a circuit
