dBm to Current Calculator

Formula

The formula to calculate the Current (I) from dBm is:

$\text{I} = \sqrt{\frac{\text{Z}}{1000}} \times 10^{\left(\frac{\text{dBm}}{20}\right)} \div \text{R}$

Where:

$\text{I}$ is the Current from dBm (amps)
$\text{Z}$ is the impedance (ohms)
$\text{dBm}$ is the dBm
$\text{R}$ is the resistance (ohms)

dBm to Current Definition

dBm to Current is a conversion that determines the current (in amps) from a given dBm value, impedance, and resistance. This conversion is important in fields such as electronics and telecommunications to understand the current flowing through a circuit based on the power level in dBm.

Example Calculation

Let's assume the following values:

dBm = 30
Impedance (Z) = 50 ohms
Resistance (R) = 10 ohms

Using the formula:

$\text{I} = \sqrt{\frac{50}{1000}} \times 10^{\left(\frac{30}{20}\right)} \div 10 = 0.71\text{ amps}$

The Current (I) is 0.71 amps.
