milliamps to amps conversionThe current I(A) in amps is equal to the current I(mA) in milliamps divided by 1000 miiliamps per amp:I(A) = I(mA) / 1000mA/ASo amps are equal to milliamps divided by 1000 miiliamps per amp:
Don’t draw more than 20 milliamps (mA) of current from your Arduino’s GPIO pins, otherwise you may damage it. Such a small current can easily switch on a transistor, and the transistor could in turn switch on a motor,relay(this is another switch controlled by a small current, except...
The LED draws about 45 milliamps with the battery producing about 1.23 volts (0.055 watts). It produces about half of the light that a candle would. The Nicad battery, when fully charged, can operate the LED for about 15 hours. Half of a candle's light is not very much, and if you...

The Precision Wideband Controller reacts to produce a pump current (Ipump) in one direction to consume the free fuel. The pump cell requires a "negative" current that goes from zero to about 2.0 milliamps when the air/fuel ratio is near 11:1. ...
What does mAh mean? Batteries common to mobile devices and Power Banks are rated on their ampere-hours, measured in milliamps to create non-decimal numbers. The mAh ratings denote capacity for power flow over time. Li-Ion & Li-Polymer ...
LEDs are known to consume low power, so the multimeter is set to measure current in milliamps (mA). Upon measuring, the two bright LEDs are shown to be consuming only 7.43mA. Similarly, buzzers do not consume much power. It is even more frugal at 2.04mA. ...
You can attach multiple sensors, but be aware of the power draw (i.e. how many milliamps each sensor uses) and the length of wire needed to connect them. (View large version) Putting The Board Together The first step is to assemble the HUZZAH board by soldering on its pin headers, ...
For my application, I am trying to measure the amount of current being drawn out of a small Lithium ion battery pack (3.7 V 500mAh), so measurements would be in the order of milliamps. What I'm trying to do with the microprocessor is to read that current...
The phone line tells a phone to ring by superimposing about 90 volts at about 20Hz AC on the normal 48V DC. When you pick the phone up and it goes "off hook", the line voltage drops to single-digit volts, and your phone should draw double-digit milliamps of current, at most. ...
