10.2 Redistribution of Charge Between Conductors

• Steps to calculate the final charge distribution between two spheres with initial charges and capacitances:

  1️⃣ Equalize the electric potentials of the spheres

  2️⃣ Calculate the final charges using $V =$$\frac{Q}{C}$

  3️⃣ Determine the charge transferred
• What happens to the electric potentials of two conductors when they are connected?

  They equalize
• During charge redistribution, conductors reach the same electric potential.
• What principle ensures no charge is created or destroyed during redistribution?

  Conservation of charge
• Larger conductors hold more charge at a given potential than smaller conductors.


  True
• When two spheres with different initial charges and capacitances are connected, their final charges are equal.

  False
• Ohm's Law states that voltage equals current divided by resistance.

  False

  True
• Steps in charge redistribution when two conductors are connected

  1️⃣ Electric potentials equalize

  2️⃣ Charge redistributes
• Match the factor affecting charge redistribution with its effect:

  Size ↔️ Larger conductors hold more charge

  Shape ↔️ Affects charge distribution

  Initial charges ↔️ Charges balance out

  Capacitance ↔️ More charge at same potential
• Conductors differ from insulators, which resist electron flow
• Steps to calculate the final charge distribution

  1️⃣ Calculate total charge

  2️⃣ Find combined capacitance

  3️⃣ Determine final potential

  4️⃣ Calculate final charges
• When two conductors are connected, their electric potentials equalize, leading to charge redistribution.
• The amount of charge transferred during redistribution depends on the capacitance of each conductor.


  True
• Conductors are contrasted with insulators, which resist the flow of electricity.
• What is one factor that influences charge redistribution?

  Initial charges
• What does the principle of conservation of charge state?

  Total charge remains constant
• The conservation of charge principle states that the total electric charge within a closed system remains constant
• Higher capacitance means more charge can be stored at the same potential
• What is a key property of conductors that facilitates easy electron flow?

  Low electrical resistance
• What are the two factors that determine the final charge distribution in conductors?
