• Two capacitors of capacitance C each are connected in parallel and then this combination

  is connected in series to a third capacitor also of capacitance C. What is the equivalent capacitance of this combination in terms of C?

  2C/3
• Two capacitors of capacitance C each are connected in parallel and then this combination is connected in series to a third capacitor also of capacitance C. This combination is connected then to the batter of voltage V. What is the potential difference on the parallel combination in terms of V?

  V/3
• Circuit is connected to the battery of some constant voltage , and switch S is also present. Switch is initially open and at some moment it is closed. How the closing of the switch influences the energy stored in the circuit?

  It increases

  
• Voltage at the ends of resistors #1 and #2 is the same, but resistor #1 has two times

  larger resistance than resistor #2. The power dissipated on resistor #1 is

  1/2 the power dissipated on resistor 2
