PART 1电路和电子工程基础 A 电路1 In the case of a resistor, the voltage-current relationship is given by Ohms law, which states that the voltage across the resistor is equal to the current through the resistor multiplied by the value of the resistance.就电阻来说,电压电流的关系由欧姆定律决定。欧姆定律指出:电阻两端的电压等于电阻上流过的电流乘以电阻值。2It may be that the inductor voltage rather than the current is the variable of interest in the circuit.或许在电路中,人们感兴趣的变量是电感电压而不是电感电流。B 三相电路1 Viewed in this light, it will be found that the
