What is the maximum voltage across this 8.2 Ω resistor at full 20 W?
Using P = V² / R, the voltage at full 20 W dissipation across 8.2 Ω is about 12.8 V. Keep the applied voltage below this level, or choose a higher-rated resistor, and allow airflow for heat removal.
How much current can this resistor carry at full power?
Using P = I² × R, the current at full 20 W dissipation is about 1.56 A. With ±5% tolerance, the real resistance lies between 7.8 Ω and 8.6 Ω, so verify the value with a multimeter for precision circuits.
