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
