Antenna Current Solution

Follow our step by step solution on how to calculate Antenna Current?

FIRST Step Consider the formula

I a = \frac{E gnd \cdot λ \cdot D}{120 \cdot π \cdot h t \cdot h r}

Next Step Substitute values of Variables

∴

I a = \frac{400V/m \cdot 90m \cdot 1200m}{120 \cdot π \cdot 10.2m \cdot 5m}

Next Step Substitute values of Constants

∴

I a = \frac{400V/m \cdot 90m \cdot 1200m}{120 \cdot 3.1416 \cdot 10.2m \cdot 5m}

Next Step Prepare to Evaluate

∴

I a = \frac{400 \cdot 90 \cdot 1200}{120 \cdot 3.1416 \cdot 10.2 \cdot 5}

Next Step Evaluate

∴

I a = 2246.89331423852A

LAST Step Rounding Answer

∴

I a = 2246.8933A

How to Evaluate Antenna Current?

Antenna Current evaluator uses Antenna Current = (Strength of Ground Wave Propagation*Wavelength*Transmitter Receiver Distance)/(120*pi*Height of Transmitter*Height of Receiver) to evaluate the Antenna Current, The Antenna Current formula is defined as the current in each part of the antenna that flows in the same direction. Such current is called antenna mode current. Antenna Current is denoted by I_a symbol.

How to evaluate Antenna Current using this online evaluator? To use this online evaluator for Antenna Current, enter Strength of Ground Wave Propagation (E_gnd), Wavelength (λ), Transmitter Receiver Distance (D), Height of Transmitter (h_t) & Height of Receiver (h_r) and hit the calculate button.

FAQs on Antenna Current

What is the formula to find Antenna Current?

The formula of Antenna Current is expressed as Antenna Current = (Strength of Ground Wave Propagation*Wavelength*Transmitter Receiver Distance)/(120*pi*Height of Transmitter*Height of Receiver). Here is an example- 2246.893 = (400*90*1200)/(120*pi*10.2*5).

How to calculate Antenna Current?

With Strength of Ground Wave Propagation (E_gnd), Wavelength (λ), Transmitter Receiver Distance (D), Height of Transmitter (h_t) & Height of Receiver (h_r) we can find Antenna Current using the formula - Antenna Current = (Strength of Ground Wave Propagation*Wavelength*Transmitter Receiver Distance)/(120*pi*Height of Transmitter*Height of Receiver). This formula also uses Archimedes' constant .

Can the Antenna Current be negative?

No, the Antenna Current, measured in Electric Current cannot be negative.
