Frequently asked questions
What is the price of Ceramic Power Resistor 5W 4Ω in Egypt?
Ceramic Power Resistor 5W 4Ω currently costs 5 EGP in Egypt.
Where can I buy Ceramic Power Resistor 5W 4Ω in Egypt?
Ceramic Power Resistor 5W 4Ω is available from RAM Electronics. Compare the offers above to find the best price.
How do I calculate the maximum current for this resistor?
Use P = I²R. At 4 Ω and 5 W, the maximum current is about 1.12 A (√(5/4)). Keep the operating current below this value and derate for heat.
Can I use it as a dummy load?
Yes, for low-power testing, provided the power source and the resistor's 5 W rating are not exceeded. Do not let the resistor dissipate more than its rated power.
