What's the resistance of 24 ~ 27 ohm 5W? How to distinguish the resistance from W?

What's the resistance of 24 ~ 27 ohm 5W? How to distinguish the resistance from W?

This kind of patch is usually plug-in. The power of the patch is not as high as this. The specific power should be found according to the size and datasheet,

What is the price of 0.1 ohm cement resistor

If it's not easy to buy, use a digital multimeter to measure a section of heating wire and wind it around a large resistance

If the standard value of a resistor is 100 ohm 5W, what is the rated voltage of the resistor

From P = u ^ 2 / R
The rated voltage is u = root (p * r) = root (5 * 100) = 10 * root 5 = 22.4 v
