The law of conservation of charge is that the net electrical charge of an isolated or overall system does not change.

• Charge is conserved
• Overall charge remains unchanged
• Charge may be created or destroyed
  • Must have positive/negative pairs

Formula

The following information was extracted from Wikipedia:

Q(t2) = Q(t1) - Qin - Qout

• Q = quantity of charge
• t = time

Characteristics of Charges

• May have: positive ( + ) or negative charge ( - )
• Proton: ( + ) positive charge
• Electron: ( - ) negative charge
• Like repels like ( + , + ) or ( - , - )
• Opposite charges attract ( + , - )
• Charge can be transferred from one object to another
