  • What is the rule for finding equivalent capacitance in a series connection of capacitors?
    Use the inverse sum rule: the inverse of the equivalent capacitance equals the sum of the inverses of individual capacitances.
  • How do capacitors in series share charge?
    Capacitors in series all have the same charge, which is also the charge on the equivalent capacitance.
  • What is the rule for finding equivalent capacitance in a parallel connection of capacitors?
    The equivalent capacitance is the sum of the individual capacitances.
  • What do capacitors in parallel share with each other?
    Capacitors in parallel share the same voltage across each capacitor.
  • What is the relationship between charge (Q), capacitance (C), and voltage (V) in a capacitor?
    The relationship is Q = C × V.
  • What is the first step in solving a capacitor circuit problem?
    Find the single equivalent capacitance for the entire circuit.
  • After finding the equivalent capacitance, what should you determine next?
    Determine the voltage and charge across the equivalent capacitor using Q = C × V.
  • How do you find the charge on each capacitor in a series configuration?
    Each capacitor in series has the same charge as the equivalent capacitance.
  • How do you find the voltage across each capacitor in a series configuration?
    Use V = Q / C for each capacitor, where Q is the shared charge and C is the individual capacitance.
  • How do you find the voltage across each capacitor in a parallel configuration?
    Each capacitor in parallel has the same voltage as the equivalent capacitance.
  • How do you find the charge on each capacitor in a parallel configuration?
    Use Q = C × V for each capacitor, where V is the shared voltage and C is the individual capacitance.
  • In the example circuit, what is the equivalent capacitance of a 1 farad and 2 farad capacitor in parallel?
    The equivalent capacitance is 1 + 2 = 3 farads.
  • How do you combine a 6 farad capacitor in series with a 3 farad equivalent capacitor?
    Use the formula: (6 × 3) / (6 + 3) = 2 farads for the equivalent capacitance.
  • If the total voltage across the circuit is 10 volts and the equivalent capacitance is 2 farads, what is the total charge?
    The total charge is Q = 2 × 10 = 20 coulombs.
  • What is the voltage across a 6 farad capacitor in series with a 3 farad equivalent capacitor, given a shared charge of 20 coulombs?
    The voltage is V = Q / C = 20 / 6 = 3.33 volts.
