From the experimental results. We can be aware of the relationship of the length to the resistance as follows: starting from 0.1 m length resistance equal to 2.2 ohm when the length is equal to 0.2 m impedance equal to 4.3 ohms.
The results We can know the relationship of the length of the resistance as long as 0.1 meters from the resistance of 2.2 ohms when a length of 0.2 meters, the resistance of 4.3 ohms.
From the results of the experiment. We can know the relationship between the length of the resistance, as follows. First length 0.1 meters resistance of 2.2 ohm. When the length of 0.2 meters resistance of 4.3 ohm.
