  hmmm
  
  anyone knows of any website that teaches you on questions about potentiometers?
  
  searched through the website but only managed to find those sites that are selling potentiometers
  
  question is how to find the length of the wire when resistors are connected to the cell..

  it's like a voltmeter
  
  but you use another system to replace the voltmeter to measure the potential difference of something

  that tool nt important one la...it is like a resistor...this one u will need to move along the length of the wire.. resistance is proportional to the length of wire...
