Charge, Current & Time

• Charge 


  A measure of the total current that flowed within a period of time.
• Q = IT

  Charge = Current x Time
• Units for charge are..

  Coulombs (C)
• 2 A of current flowed for 30 s.

  How much charge?

  Q = IT

  Q = 2 X 30

  Q = 60
• 30 C of charge flowed through a wire in 10 s

  What is the current in the wire?

  Q = IT

  I = Q / T

  I = 30 / 10

  I = 3 A
