Question

A 2.14 μF capacitor and a 5.62 μF capacitor are connected in series across an 18.0 V battery. What voltage would be required to charge a parallel combination of the same two capacitors to the same total energy?

Answer #1

therefore , V^{2} = (5.02 x 10^{-4}) / (7.76 x
10^{-6})

= 64. 69

thus , V = 64. 69

**= 8.04 V (answer)**

Four capacitors are placed within an 18.0 V circuit as
follows:
Two capacitors 30.0 μF and 65.0 μF are connected in series with
the battery, followed by two capacitors 45.0 μF and 80.0 μF
connected in parallel.

performing any calculations!),
How the equivalent capacitance in this circuit would change if
the two capacitors originally in series were now connected in
parallel, and the two capacitors originally connected in parallel
were now connected...

Two capacitors, one of 5 μF and the other of 8 μF, connected in
parallel, are charged with a 12 volt battery. The battery is then
disconnected, and while the capacitors remain connected in
parallel, a dielectric with constant 2 is inserted between the
plates of the 8 μF capacitor. What is the voltage across this
capacitor after the dielectric is inserted?
