• Units Coulombs - symbol C
• 6.25 x 1018 electrons
• 1 electron has a charge of -1.6 x 10-19 C
• 1 proton has a charge of +1.6 x 10-19 C
• Notation
• Constant charge - Q
• Instantaneous charge -  or
• Law of Conservation of Charge
• Charge cannot be created or destroyed, only transferred

 

93.75x1016/(6.25x1018) C

 

2 x 6.25x1018 = 1.26x1019
