电阻测量方法多种多样,但其核心仍然是欧姆定律,即R=U/I.也就是求某一电阻的阻值,只要知道它两端电压和通过它的电流即可.如果按电阻测量的常用原理来分有:伏安法(也叫欧姆定律法)、半偏法和替代法;如果按使用的测量仪表来分有:伏安法、电压表测电阻法、电流表测电阻法.不同的测量原理、不同的测量仪表,设计测量电路 Resistance measurement methods vary, but the core is still Ohm’s law, that is, R = U / I. That is to find the resistance of a resistor, as long as the voltage across it and the current through it can be measured by resistance The common principle to have: voltammetry (also known as Ohm’s law), half-partial law and alternative method; if used by measuring instruments to have: voltammetry, voltmeter resistance method, ammeter resistance method. Different measurement principles, different measuring instruments, design and measurement circuit
