Total Antenna Resistance Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
Radiation Resistance - (Measured in Ohm) - Radiation resistance is an effective resistance, due to the power carried away from the antenna as radio waves.

STEP 1: Convert Input(s) to Base Unit

Ohmic Resistance: 2.5 Ohm --> 2.5 Ohm No Conversion Required
Radiation Resistance: 2.25 Ohm --> 2.25 Ohm No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_t = R_ohm+R_rad --> 2.5+2.25

Evaluating ... ...

R_t = 4.75

STEP 3: Convert Result to Output's Unit

4.75 Ohm --> No Conversion Required

FINAL ANSWER

4.75 Ohm <-- Total Antenna Resistance
