本文主要介绍了直流电英文单词，选择的方面对这些单词进行详细阐述。文章以、、和展开描述，最后通过对直流电英文单词进行概括。

1. Voltage（电压）

Voltage is a fundamental concept in direct current (DC) electricity. It refers to the electric potential difference between two points in an electrical circuit. The unit of voltage is the volt (V). In a DC circuit, voltage is constant and does not change with time.

Direct current电压是直流电（DC）电力中的一个基本概念。它指的是电路中两个点之间的电势差。电压的单位是伏特（V）。在直流电路中，电压是恒定的，不随时间变化。

2. Current（电流）

Current is the flow of electric charge in a circuit. It is measured in amperes (A). In a DC circuit, current flows in one direction only and does not change with time. The direction of current is defined as the direction in which positive charges flow.

电流是电荷在电路中的流动。它的单位是安培（A）。在直流电路中，电流只在一个方向上流动，不随时间变化。电流的方向被定义为正电荷流动的方向。

3. Resistance（电阻）

Resistance is a property of a material or component that opposes the flow of electric current. It is measured in ohms (Ω). In a DC circuit, resistance limits the amount of current that can flow. Ohm's Law states that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance.

电阻是材料或元件阻碍电流流动的特性。它的单位是欧姆（Ω）。在直流电路中，电阻限制了电流的流动量。欧姆定律规定电路中的电流与电压成正比，与电阻成反比。

4. Power（功率）

Power is the rate at which work is done or energy is transferred in an electrical circuit. It is measured in watts (W). In a DC circuit, power is calculated by multiplying the voltage and current. Power can also be calculated using Ohm's Law by multiplying the current squared by the resistance.

功率是电路中工作完成或能量传递的速率。它的单位是瓦特（W）。在直流电路中，功率通过电压和电流相乘来计算。功率也可以使用欧姆定律通过电流的平方乘以电阻来计算。

5. Circuit（电路）

A circuit is a closed loop through which electric current can flow. It consists of various components such as resistors, capacitors, and inductors connected by conductive wires. In a DC circuit, the current flows in a single direction from the positive terminal to the negative terminal of a power source.

电路是一个闭合的回路，电流可以通过它流动。它由电阻器、电容器和电感器等各种元件通过导电线连接而成。在直流电路中，电流从电源的正极流向负极，只在一个方向上流动。

本文详细介绍了直流电英文单词的相关概念和术语，包括电压、电流、电阻、功率和电路。这些单词是理解和研究直流电的基础。通过掌握这些概念，我们可以更好地理解直流电的工作原理和应用。
