Four students are each given an identical resistor and asked to find its resistance. They each measure the potential difference across the resistor and the current in it. One student makes a mistake.
Which row shows the results of the student that makes a mistake?
1 )
potential difference/V:1.2 / current /A:0.500
potential difference/V:2.4 / current /A:1.100
3 )
potential difference/V:1.5 / current /A:0.625
4 )
potential difference/V:3.0 / current /A:1.250
تحلیل ویدئویی تست
منتظریم اولین نفر تحلیلش کنه!
