(1)Ohm’s law states that the voltage across a resistor is directly proportional to the current flowing through the resistor. The constant of proportionality is the resistance value of the resistor in ohms. 流过电路里电阻的电流,与加在电阻两端的电压成正比,与电阻的阻值成反比。这就是欧姆定律。
Ohm’s Law states the voltage across a resistor,R(or impedance,Z)is directly proportional to the current passing through it (the resistance/impedance is the proportionality constant).DC:v=iRAC:V=IZOhm’s Law by itself is not sufficient to analyze circuits.However,when it is coupled with ...
You can use this relationship to calculate the voltage across a resistor. Step 1 Consider the resistor that you want to calculate the voltage across. Suppose, as an example, that you are considering a 4 Ohm resistor. Step 2 Measure the current passing through the wire in the circuit immediat...
If a sinewave voltage is applied,the voltage across the resistor always leads the voltage across the capacitor by exactly 90 deg.,independent of the frequency.[5] This is because the current,which flows through the resistor,also flows through the capacitor and since the voltage across a ...
The voltage (V) across the resistor (R) was recorded at 20 min intervals using a Paperless Recorder . The current (I) was calculated by Ohm’s law (I = V/R). The current and power densities were normalized bythe total surface area per anode module (A). The coulombic efficiency (CE...
For example, if the voltage across a resistor is 5 V and the current through the resistor is 0.5 A, the resistor is transferring 2.5 W of power (as heat) to the surrounding environment. However, in most cases, we are not intending to transfer energy. We simply want to design a funct...

- The voltage across the resistor is 5 volts. 电阻器上的电压是5伏。 - The electrician measured the voltage resistance of the circuit. 电工测量了电路的电压阻抗。 3. Voltage是能量的量,它能够产生电流,而volt是测量电势差或电压的单位。 例句: - The high voltage in the power line produces stro...
anot a dry eye in the house 不是干眼病在房子里[translate] aWhen the switch was closed,the current flowing through the resistor was read from the ammeter and the voltage across the resistor was read from the voltmeter. 当开关是闭合的,流经电阻器的潮流从安倍计读了,并且电压横跨电阻器从电压表...
