What is the abbreviation for milli amp direct current?
Milliamps = mA.
How much electric current can cause death?
6 MilliAmps across the heart.
Unit used to measure the magnitude of current?
Ammeter. Will read in Amps or milliamps.
If the current is 33 milliamps and the resistance is750 ohms what is the voltage?
24.8 Volts
Why is a GFCI receptacle set for 5 milli-Ampere?
Milliamp dangersLess than 1/2 milliamp no sensation1/2 to 2 milliamps Threshold of perception2 to 10 milliamps muscular contraction5 to 25 milliamps painful shock (may not be able to let go)Over 25 milliamps Could be violent muscular contraction50 to 100 milliamps Ventricular fibrillationover 100 paralysis of breathing. You can see above, if the circuit was not disconnected the damage that milliamps currents can cause. 2 to 10 milliamps will cause muscular contraction but the circuit is opened in 1/40th of a second so that no damage will be caused. The electronic metering of the current at a level of 5 milliamps (.005 amps) was picked by convention as a safe level to trip the breaker. If there is a difference of 5 milliamps of the current entering the circuit and leaving the circuit, the logic states that the current must be going some place else which could be detrimental to someones health, so the breaker shuts off the current to the load.
What current rate in volts and amps is life threatining for human being?
The dangerous amount of current is not in the amp range but in the milliamp range as per the following. One amp is equal to 1000 milliampsMilliamps are dangerousLess than 1/2 milliamp no sensation1/2 to 2 milliamps Threshold of perception2 to 10 milliamps muscular contraction5 to 25 milliamps painful shock (may not be able to let go)Over 25 milliamps Could be violent muscular contraction50 to 100 milliamps Ventricular fibrillationover 100 paralysis of breathing.
What is the unite of current?
Current is measured with an ammeter and in units called amperes, or amps.ampsamperes
What is the max output current rating of a Programmable Logic Control?
It depends on the specification of the PLC. One with a fanout of 10 into a standard TTL load can sink 16 milliamps and source 4 milliamps.
What does MA mean on a multimeter?
MA or mA on a multimeter designates milliamps, or "thousandths" of an amp of current flow.
What level of electrical current is safe for the human body?
Less than 5 milliamps @ 110 volt.
A movement of charges in response to a potential difference is called what?
Current and it is measured in amps, milliamps or perhaps microamps.
What effect would a current of greater than 0.2 amp have on your body?
In your question .2 amps is equal to 200 mAMilliamp are dangerousLess than 1/2 milliamp no sensation1/2 to 2 milliamps Threshold of perception2 to 10 milliamps muscular contraction5 to 25 milliamps painful shock (may not be able to let go)Over 25 milliamps Could be violent muscular contraction50 to 100 milliamps Ventricular fibrillationover 100 paralysis of breathing.
