(a) When capacitors are connected in series, all capacitors have the same charge the voltage across each capacitor is the same the total capacitance of the system increases (b) When capacitors are connected in parallel, all capacitors have the same charge the voltage across each capacitor is the same the total capacitance of the system decreases

#87: The flash unit in a camera uses a special circuit to “step up” the 3.0 V from the batteries to 300 V, which charges a capacitor. The capacitor is then discharged through a flashlamp. The discharge takes 10 ms, and the average power dissipated in the flashlamp is 105 W. What is the capacitance of the capacitor?

The volume enclosed by the plates of a parallel plate capacitor is given by the equation Volume = Ad. If one doubles the area, A, of the plates and reduces the plate separation, d, by a factor of two so that the volume remains the same, the capacitance will do which of the following? decrease by a factor of 4 O increase by a factor of 4 increase by a factor of 2 decrease by a factor of 2 O remain constant

If three unequal capacitors are connected in series, what can we say about the equivalent capacitance of these capacitors? It is greater than any of the individual capacitances. It is less than any of the individual capacitances. It is somewhere between the largest and smallest capacitances. We can't determine anything without knowing the values of the individual capacitances.

Could some one explain this thanks
