## Question:

A 21 V battery is connected across capacitors of capacitances C1 = C6 = 4.0 {eq}\mu F {/eq} and C3 = C5 = 2.5 {eq}\mu F {/eq}, C2 = 2.5 {eq}\mu F {/eq}, C4 = 4.0 {eq}\mu F {/eq}. What is the potential V3 across on capacitor 3?

## Voltage source

Voltage sources are the most common sources, which deliver electrical power. This voltage source may be Dc or Ac. If the voltage source is constant, i.e., time-invariant, it is called a dc voltage source, for example, a battery. When the voltage source is alternating in nature, it is called an AC voltage source.

Given data:

• the magnitude of the voltage source is: {eq}V = 21{\rm{V}} {/eq}
• The value of capacitances is {eq}{C_1} = {C_{_6}} = 4.0\,{\rm{\mu F =...
