Definition: Current is the flow of electric charge through a conductor, measured in amperes (A).
Translation: 电流是电荷通过导体的流动，单位为安培（A）。
3.
Resistance (电阻)
Definition: Resistance is the opposition to the flow of electric current, measured in ohms (Ω).
Translation: 电阻是电流流动的阻碍，单位为欧姆（Ω）。
4.
Power (功率)
Definition: Power is the rate at which work is done or energy is transferred, measured in watts (W).
Translation: 功率是工作完成或能量转移的速率，单位为瓦特（W）。
5.
Circuit (电路)
Definition: A circuit is a closed loop through which an electric current can flow.
Translation: 电路是一个闭合回路，电流可以流过其中。
6.
Alternating Current (交流电流)
Definition: Alternating current periodically reverses direction, commonly used in household electrical outlets.
Translation: 交流电流周期性地改变方向，常用于家庭电源插座。
7.
Direct Current (直流电流)
Definition: Direct current flows only in one direction, commonly used in batteries.
Translation: 直流电流只在一个方向流动，常用于电池。
8.
Transformer (变压器)
