MEP EP#326: The Infinite Finite Grid

PART 2 : Is there a macgyver way to measure voltage without a multimeter?

• Lots of great suggestions in our slack channel
  
  
  • Recreating older devices before digital multimeters where available
  
  
  • Galvanometer
  
  
  • Electrostatic Voltmeter
  
  
  • Most of these require lots of experimentation or other precision devices to calibrate
  
  
  
  


• Let's explore the electrolysis method further
  
  
  • Tools and measuring devices required
    
    
    • Watch / time keeping
    
    
    • Container of known volume
    
    
    
    
  
  
  • Materials
    
    
    • Distilled Water
    
    
    
    
  
  
  • Equations from Purdue
  
  
  • Amps & Time <-> Coulombs <-> Faradays <-> Moles of Electrons
