A bulb has a power of 60 watts and a voltage of 12 volts. What is the current flowing through the bulb? A. 5 A B. 6 A C. 7 A D. 8 A 相关知识点: 试题来源: 解析 A。由 P = UI,可得 I = P / U = 60 / 12 = 5 A。
In the same way that you can find out how many lux is a 1000 watt bulb, after setting up the values for luminous efficacy and the surface area of your illuminated object. How do I convert 300 lux to watts? To convert 300 lux to watts in our lux to watts calculator, take the follow...
As low-wattage bulbs become more commonplace, we need a better way of measuring their output. This is where the lumen comes in. Figures for lumens appear on the packaging of all light bulbs and allow us to compare the brightness (or dimness) of a bulb. Let's imagine that you are ...
The old days of choosing light bulbs by wattage are over. With today’s modern LED bulbs, we instead need to focus on lumens. But what is a lumen? We’ll explain that, and then you can use our lumens to watts conversion chart to select the right LED bulb every time. ...
Inductive load: The type of load generated by pretty much all devices that contain moving parts and by all devices with any sort of coil of wire that produces a magnetic field.If your device falls under the 1st (a light bulb, radiant heater, kettle, etc.) or 2nd (a laptop/cell phone...

headlight bulb works on just 2 watts of power. Because the bulb uses such a low amount of power. It also means that the bulb is much more efficient than its halogen counterpart. The SEALIGHT 9005 LED bulb gives a brighter. And whiter light, which will not hurt the night vision of the...

Monthly Energy Consumption: If you use the light bulb every day, it would be 0.05 kWh/day * 30 days = 1.5 kWh per month. Here we learn that watts alone do not tell the story about energy usage. Despite the microwave having a wattage 100 times greater than that of the LED light bulb...
a100-watt LED lightbulbuses significantly less electricity than a 750-watt microwave oven. You can see the difference if you switch between the two devices while monitoring the home's electric meter. With the microwave oven, the meter will run rapidly, while with the LED bulb, it will move ...
