Practice questions

• Time constant = C * R

  R calculate through resistivity

  = 217 * 0.010 = 2.2s


  Question:

  
• Electrons are removed from X and deposited on Y (1)

  As a result X becomes positively charged Y becomes negative (1)

  X and Y acquire equal but opposite charges as the same number of electrons are removed and deposited (1)
