"Note: 3V 10mA" vs. "Note: 3V 100mA''?
My wireless keyboard office has a rating of 3 V and 10 mA, while the wireless optical mouse is 3V and 100mA. I was not a science major in my school years: 1) Can you explain the meaning of the difference between 3V 10mA 3V and 100mA? (I used 1.2V 2500mA rechargeable) 2) when the mouse does not work because of 2 x 1.2 V batteries, a battery is measured 1.1V, while the other is 0.9V. Why? Any feedback is appreciated. 3) I use both batteries died to make my mini vacuum cleaner and Vacuum for work hours!
1] The difference between 3V and 3V 10 mA 100 mA is: The first note using your keyboard uses a 3v battery volts and consumes about 10 mA current for function. (which is 10 millionths of an ampere). The second (mouse) Assessment is 3V, but draws 100 milliamps (or 100 millionths amplifier). 10 times more power, but at the same voltage. A good analogy is with a garden hose. If you put the hose on the slow, a small amount water passes through. When the pressure is increased, more water is passed in the same area. This is the analogy being. 2] Batteries May show tightness, but now they are also important. The batteries can be about 2 volts between them, but later left in them does not to "push" the line voltage.
