How much is the resistance of the heating tube of Jiuyang electric casserole normal?
The resistance of the heating tube of Jiuyang electric casserole is 48.4 ohms, which is normal. Household heating pipes have many uses, such as100W,150W, 300W, 500W,1000W, etc. For a voltage of 220 volts. For example, the resistance value of 1000 watt heating tube is the square of voltage divided by wattage, which is 48.4 ohms. General 1000W is about 48 ohms, 1500W is about 32 ohms, and 2000W is about 24 ohms. And because the cold resistance is slightly lower, it will be slightly lower than the above value when testing.
