What is the maximum voltage this 18 Ω resistor can take at full power?
Using P = V² / R, the voltage at full 20 W dissipation across 18 Ω is about 19 V. Stay below this value, or use a higher-rated resistor, and provide adequate cooling or clearance for heat.
Can it be used as a dummy load for testing power supplies?
Yes, wire wound cement resistors are commonly used as dummy loads. Confirm the current and power at your test voltage stay within the 20 W rating, and mount the resistor so heat can dissipate safely.
