一、依据电路图描述测量方法图 1例 1 有一阻值已看不清楚的电阻Ｒｘ,要测出它的阻值 .某同学利用手边的电池组、电流表、一个已知阻值的电阻Ｒ0 和若干导线 ,设计了一种用多种方法测量Ｒｘ 的电路 ,如图 1所示 .请你分析一下该电路能用哪些方法测出Ｒｘ 的阻值 .简述你的方法
First, according to the circuit diagram to describe the measurement method Figure 1 Example 1 A resistance Rx has not clearly seen the resistance, to measure its resistance. A classmate using the battery pack at hand, ammeter, a resistor with a known resistance R0 and several The wire, designed a circuit that uses a variety of methods to measure Rx, as shown in Figure 1. Please analyze how the circuit can be used to measure the resistance of Rx. Briefly describe your method
