Question

1) Six 9.3??F capacitors are connected in parallel.

What is the equivalent capacitance?

Ceq = ?F


What is their equivalent capacitance if connected in series?

Ceq = ?F


2) A circuit contains a single 260?pF capacitor hooked across a battery. It is desired to store three of two capacitors by adding a single capacitor to this one.


What would its value be?

C = pF


3) A power supply has a fixed output voltage of 12.0 V, but you need VT=5.0V for an experiment.

R2 =   ?


What will the terminal voltage VT be if you connect a load to the 5.0V terminal, assuming the load has a resistance of 4.0? ?

VT =   V

F capacitors are connected in parallel. What is the equivalent capacitance? What is their equivalent capacitance if connected in series? A circuit contains a single 260?pF capacitor hooked across a battery. It is desired to store three of two capacitors by adding a single capacitor to this one. What would its value be? A power supply has a fixed output voltage of 12.0 V, but you need VT=5.0V for an experiment. Using the voltage divider shown in the figure , what should R2 be if R1 is 16.0? What will the terminal voltage VT be if you connect a load to the 5.0V terminal, assuming the load has a resistance of 4.0? ?

Explanation / Answer

1) Six 9.3??F capacitors are connected in parallel.

What is the equivalent capacitance?

Ceq = 9.3*6 = 55.8 uF

if connected in series,

1/Ceq = 6/9.3

Ceq = 9.3/6 = 1.55 uF


2) A circuit contains a single 260?pF capacitor hooked across a battery. It is desired to store three of two capacitors by adding a single capacitor to this one.


question is not clear

What would its value be?

C = pF


Req = 16 + (11.428 | 4) = 16 + 11.428*4/(15.428) = 18.9629 Ohm

i = 12 / 18.9629 = 0.6328 A

VT = 0.6328*11.428*4/(15.428) = 1.8749 V
