It depends on your proximity to the circuit under consideration and your
electrical relationship to it. If your body is a part of the circuit, and the
current happens to flow through or near your heart, then as little as
0.015 Amp can ... as they say ... cause death. If, on the other hand,
you are not a part of the circuit and the current does not flow through
you, then there is no danger regardless of the magnitude of the current.

Why 30 to 40 volts of DC Is dangerous to us?
Volts alone is not dangerous, but volts does causes amps. Amps can be dangerous to you if it flows through your body. That's because your brain, your nerves, and your muscles ... including your heart ... all operate on tiny natural volts and amps. They can all go haywire when big ones get in from outside your body.
What happens to the currents in a circuit?
a cell pushes electric currents around a circuit.If there are two or more cells then more currents will flow through them.
What can you increase by adding more cells in a circuit?
amps
What is the current produced when a voltage of 60 V is applied to a resistance of 15?
As the question didn't say whether the resistors were in series of parallel, perhaps both eventualities should be looked at. In series, the total resistance is the sum of the series resistors. The 30-ohm and 60-ohm resistors sum to 90 ohms. Total current will be voltage divided by resistance. The 220 volts applied divided by the 90 ohms will give 2.44 amps (2 4/9ths amps). In parallel, each resistor is connected indendently across the 220-volt source. Each one will "feel" the 220 volts and draw current accordingly. Since current equals voltage divided by resistance (just like always), we have to make the calculation for each resistor. The 220 divided by 30 equals 7.33 amps (7 1/3 amps). The 220 divided by 60 equals 3.66 amps (3 2/3 amps). The two branch currents each represent a part of the total circuit current, we have to find the sum of the branch currents to find the total current. Our 7.33 plus 3.66 amps sums to 11 amps.
Why is a 'short-circuit'in a mains circuit dangerous?
It is potentially dangerous because it provides a low-resistance path across the supply voltage. That causes excessive current to flow, and if all is well a fuse or circuit-breaker will operate to shut off the supply. Without that there might be enough current to cause a fire.
Are volts or amps more dangerous?
no
What do you measure currents in?
Currents are measured in amps being I
Are rip currents dangerous?
Yes, rip currents are very dangerous. Several people die each year after being caught in these currents.

What is the smallest unit of measure for current?
There is only one unit of measure for current: the ampere. All currents are measured in amps or fractions of amps or their equivalent.
What unit is current measure in?
Electrical currents are measured in a unit called amperes, which are abbreviated as "amps." There are two different designations that measure currents: direct currents (DC) and alternating currents (AC). Amperes are coulombs per second. Amperes are electrical current units that are part of the meter-kilogram-second system. A flow of one coulomb per second is equivalent to one single ampere.
If 2 amps of current enter a node of a parallel circuit how many amps must leave the node?
The nodal currents must sum to zero (Kirchhoff's current law). So the answer is 2 amps.
What Is a device that protects dangerous currents?
I THINK it's a transformer
When are rip currents strongest and most dangerous?
Rip currents are channeled currents of water flowing away from the shore, which pull people away to deeper waters. The speed varies but can quickly increase and become very dangerous to even strong swimmers.
How many amps is 26 awg wire rated for?
Copper wire current ratings assume 10 amps per mm2 for currents up to a few amps. 26 AWG wire has a cross sectional area of 0.13 mm2 so this logic says 1.3 amps.
Is any dangerous fish or animals in Mississippi river Illinois?
There are very dangerous currents and you may encounter human obstacles.
What is currnt measured in?
Electrical current is measured in amperes, or amps for short. Smaller currents might be measured in milliamps or microamps.
