Voltage from RF power

The Voltage from RF Power and Impedance calculator computes the volts from RF power based on the impedance.

INSTRUCTIONS: Choose units and enter the following:

• (R) RF Power
• (I) Impedance

Voltage from RF Power and Impedance (V): The calculator returns the current in volts.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for the Voltage from RF Power and Impedance is:

   `V = sqrt(R*P)`

where:

• V = Voltage from RF Power
• R = RF Power
• I = Impedance
