Why should I put capacitors in parallel?

Answer 1

Actually, there is no right or wrong answer here. Capacitors can be connected in series or parallel. The choice depends on what the circuit needs to accomplish. It may also depend on the specifications of the capacitors.

Connecting two capacitors in parallel results in a capacitance that is the sum of the capacitance of each.

#C = C_1 + C_2#

Connecting two capacitors in series requires a little more math.

#C = 1/(1/C_1 + 1/C_2)#

Now let's look at how that math works out if we choose a value of 5 for both #C_1# and #C_2#.

Parallel: #C = 5 + 5 = 10#
Series: #C = 1/(1/5 + 1/5) = 1/(2/5) = 5/2 = 2.5#

Why would you want each of these circuits?
If the total capacitance required were 2.5 or 10, the choice is clear.

But it might also be the case that your circuit runs at 100 Volts and these components are only capable of operating at 60 Volts. Two capacitors in series would allow you to connect across a 120 Volt connection.

Answer 2

Capacitors are put in parallel to increase the total capacitance of the circuit and to provide a larger charge storage capacity. This configuration allows for more efficient energy storage and discharge, especially in applications where high capacitance is required. Additionally, putting capacitors in parallel can also help distribute the load evenly across multiple capacitors, leading to better reliability and performance in the circuit.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
