Output Voltage (V):

A voltage multiplier is an electrical circuit that converts an AC voltage from a lower value to a higher value. Voltage multipliers are commonly used in applications where high voltage is needed but the current requirement is low. They are widely used in devices such as CRT monitors, oscilloscopes, and various high-voltage power supplies.

## Formula

The output voltage (VoutV_{out}Vout​) of a voltage multiplier can be calculated using the following formula:

Vout=Vin×nV_{out} = V_{in} \times nVout​=Vin​×n

where:

• VoutV_{out}Vout​ is the output voltage.
• VinV_{in}Vin​ is the input voltage.
• nnn is the number of multiplier stages.
