4-20 milliamps refers to a standard analog signal that is used in many instrumentation circles. For example a tank level transmitter will send a 4 milliamp signal when the tank is empty and a 20 milliamp when the tank is full. 12 milliamp would indicate 1/2 full. Anything less than 4 milliamps is considered a broken wire or failed powersupply. This is the standard often used in the US. Germany often uses 0 to 20 millamp signals.
Your total milliamp range is 4 to 20 milliamps. 4 Ma being 0mmH2o and 20 Ma being 2500mmH2o. So 1250mmH2o is 50% which is equivalent to 12Ma signal.
30 ma will not hurt you but 4 kv or 4000 volts will certainly kill you for it will push far more than 30 ma through your body-wet or dry! <<>> Taking any amount of AC voltage from hand to hand is dangerous. This is because the path the voltage takes is across the chest in the location of your heart. Small voltages can stop the heart from beating. Milliamps are dangerous and will hurt you as shown below; Less than 1/2 milliamp no sensation 1/2 to 2 milliamps Threshold of perception 2 to 10 milliamps muscular contraction 5 to 25 milliamps painful shock (may not be able to let go) Over 25 milliamps Could be violent muscular contraction 50 to 100 milliamps Ventricular fibrillation over 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.
900 milliamps.
There are 1000 milliamps (mA) in 1 Amp, so the answer is 4000.

Your total milliamp range is 4 to 20 milliamps. 4 Ma being 0mmH2o and 20 Ma being 2500mmH2o. So 1250mmH2o is 50% which is equivalent to 12Ma signal.
The answer depends on the units which were used for 0.026. For example, 0.026 milliamps would be 0.026 milliamps while 0.026 microamps would be 0.000026 milliamps.
20 - 4 or 4 - 20 , whichever is not negative. In this case it is 20 - 4 = +16
1 amp = 1000 milliamps so 1700 milliamps = 1.7 amps.
ma stands for milliamp. The prefix 'milli is equivalent to .001 So 1 amp would be 1000 milliamps and 20 milliamps would be .02 amps
If you mean: 4/20 then it is 1/5 in its simplest form
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.
There are zero milliamps in 12 watts.
There are 0.075 amps in 75 milliamps.
