Ohmic Resistance Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Ohmic Resistance - (Measured in Ohm) - Ohmic resistance is the material's opposition to the flow of electric current.
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.
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

Total Antenna Resistance: 4.75 Ohm --> 4.75 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_ohm = R_t-R_rad --> 4.75-2.25

Evaluating ... ...
