He recently posted a few videos on his EEVblog exploring the reasons why Fluke voltmeters are so expensive. In the process, he stumbled upon an interesting hack for the Fluke 77. The Fluke 77 was ...

This was a lesson learned in the times of LPT and COM ports, where factory-made peripherals and DIY boards alike had to pull peculiar tricks to get a few milliamps, often tapping data lines.

mAVΩ Red To measure voltage, resistance, temperature, and sometimes milliamps and microamps. mAµA Red To measure milliamps ...

Let's explore. mAh and Wh express battery capacity. If a battery has a capacity of 5,000mAh, it can provide 5,000 milliamps of current for one hour before it runs out (5,000mA x 1h = 5,000mAh).

Many everyday currents for small household appliances will be measured in milliamps, mA: 1,000 mA = 1 A.

There are two tabs on this chart, one showing battery life (in minutes) and one showing the capacity of the battery (in milliamp hours). You can see a clear and impressive increase in battery life ...

Many everyday currents for small household appliances will be measured in milliamps, mA: 1,000 mA = 1 A. A charge of 5.0 C is transferred through a wire in 20 s. Calculate the current in the wire.
