Frequently asked questions
What is the price of Power Resistor 20W 1Ω in Egypt?
Power Resistor 20W 1Ω currently costs 16 EGP in Egypt.
Where can I buy Power Resistor 20W 1Ω in Egypt?
Power Resistor 20W 1Ω is available from Makers Electronics. Compare the offers above to find the best price.
What maximum current can it carry at 1 Ω?
From P = I²R, the maximum current at full 20 W dissipation is about 4.5 A (√(20/1) ≈ 4.47 A). Stay below this to keep dissipation within the rating.
Does it need a heatsink?
The 20 W rating assumes adequate cooling. For sustained operation near the rated power, mount it on a heatsink or in free air with good ventilation, and keep heat-sensitive parts away from it.
