1. They are typically in the order of some milliamperes . 2. My phone line can supply up to 38 milliamperes . 3. Current density reached 100 milliamperes / cm2. 4. Relatively low sustained arc currents of a few milliamperes can cause eventual aging degradation of the cable. 5. Accurate measurement of low currents ( a few milliamperes ) with a current transformer clamp is more difficult. 6. They have built a 0.6-volt biofuel cell that can deliver currents of as much as 17 milliamperes . 7. In 2014 researchers identified a liquid sodium-cesium alloy that operates at 1 produced 420 milliampere -hours per gram. 8. Practical tunnel diodes operate at a few milliamperes and a few tenths of a volt, making them low-power devices. 9. The strong charge needed for radial confinement of the ions requires large electron beam currents of tens up to hundreds of milliampere . 10. Therefore, switching currents are often required in the range of several hundred milliamperes , or even in the range of amperes.
