The voltage at both ends of a small flashlight bulb is 2.5V, and the measured current is 250mA. What is the resistance of the small flashlight bulb?

The voltage at both ends of a small flashlight bulb is 2.5V, and the measured current is 250mA. What is the resistance of the small flashlight bulb?


The current through the bulb: I = 250mA = 0.25A, the resistance of the bulb: r = UI = 2.5v0.25a = 10 Ω. A: the resistance of the bulb is 10 Ω



How many tons is 8000 grams


8 / 1000 tons 0.008 tons



Unit conversion: how many milligrams is one gram equal to?


Weight unit:
1kg = 1000g 1kg = 1000g = 1kg
1g = 1000mg, 1g = 1000mg
1t = 1000kg 1t = 1000kg = 1000kg
Recently, I took medicine and found that Mg is often used in the label of medicine
