1. 第一个空需填不定冠词"a",因voltage是可数名词且首次提及; 2. 第二个空需"closed"(闭合),只有闭合电路才会有电流; 3. 第三个空填"an",因electric以元音开头; 4. 最后一个填定冠词"the",特指前文提到的同一电路。 完整物理逻辑为:闭合电路中施加电压才能形成电流,满足欧姆定律应用条件。
The voltage across a resistor in a circuit is 12 volts and the current through it is 2 amperes. What is the resistance of the resistor? A. 6 ohms B. 8 ohms C. 10 ohms D. 14 ohms 相关知识点: 试题来源: 解析 A。解析:根据欧姆定律,电阻等于电压除以电流,12 伏除以 2 安等于 6 欧姆。

Current to Voltage Conversion: Converts a current source into a voltage source by applying Ohm’s law to determine the voltage across an open circuit. Circuit Simplification: Source transformation allows easier analysis and understanding of complex circuits by changing the type of sources without alter...
The circuit diagram below shows a resistor acting as a simple voltage tocurrentconverter. In this diagram, voltage and current are represented by bars and loops, respectively. But practically, the output current of this converter depends directly on thevoltage dropacross the connected load in additi...
