## Capacitance Multiplier Formula

The following formula is used to calculate the output capacitance:

C_{out} = C_{in} * M

Variables:

- C_out is the output capacitance (μF)
- C_in is the input capacitance (μF)
- M is the multiplier

To calculate the output capacitance, multiply the input capacitance by the multiplier.

## What is a Capacitance Multiplier?

A capacitance multiplier is an electronic circuit that uses an active device (like a transistor) to make a small capacitor function like a capacitor that is much larger. This is useful in power supply filters where large capacitance values are needed to reduce ripple voltage but physical size or cost of large capacitors is prohibitive.

## How to Calculate Output Capacitance?

The following steps outline how to calculate the output capacitance using a capacitance multiplier.

- First, determine the input capacitance (C_in) in microfarads (μF).
- Next, determine the multiplier (M).
- Use the formula from above = C_out = C_in * M.
- Finally, calculate the output capacitance (C_out) in microfarads (μF).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

Input capacitance (C_in) = 100 μF

Multiplier (M) = 10
