Radiation Resistance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radiation Resistance = Total Antenna Resistance-Ohmic Resistance
R_rad = R_t-R_ohm
This formula uses 3 Variables

Variables Used

Radiation Resistance - (Measured in Ohm) - Radiation resistance is an effective resistance, due to the power carried away from the antenna as radio waves.
Total Antenna Resistance - (Measured in Ohm) - Total Antenna Resistance is defined as the electrical resistance of an antenna is composed of its ohmic resistance plus its radiation resistance.
Ohmic Resistance - (Measured in Ohm) - Ohmic resistance is the material's opposition to the flow of electric current.

STEP 1: Convert Input(s) to Base Unit

Total Antenna Resistance: 4.75 Ohm --> 4.75 Ohm No Conversion Required
Ohmic Resistance: 2.5 Ohm --> 2.5 Ohm No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_rad = R_t-R_ohm --> 4.75-2.5

Evaluating ... ...

R_rad = 2.25

STEP 3: Convert Result to Output's Unit

2.25 Ohm --> No Conversion Required

FINAL ANSWER

2.25 Ohm <-- Radiation Resistance
