How many volts is generally the most dangerous to work with because it causes a current flow of 100 to 200 milliamperes through the body?
Generally, voltages as low as 50 volts can be dangerous because they can cause a current flow of 100 to 200 milliamperes through the body under certain conditions. However, the level of danger depends on various factors, including the path the current takes through the body, the duration of exposure, and individual health conditions. Higher voltages increase the risk further, making it crucial to exercise caution when working with electrical systems.

Generally any current flow above what is considered dangerous?
Generally, any current flow above 10 milliamperes (mA) is considered potentially dangerous to human safety. At this level, it can cause muscle contractions and impair a person's ability to let go of an electrified object. Currents above 100 mA can lead to serious injuries, including ventricular fibrillation, which can be fatal without immediate medical intervention. Always exercise caution around electrical sources to minimize the risk of electric shock.
What is 0.005 ampere current the same as?
A current of 0.005 ampere is the same as 5 milliamperes (mA). The conversion is based on the fact that 1 ampere equals 1,000 milliamperes, so multiplying 0.005 by 1,000 gives you 5 mA. This level of current is commonly used in low-power electronic circuits.
Why ac current is more dangerous than dc?
no actually dc current is more dangerous than ac because dc is a direct current and has no current zero condition ,which is very dangerous and do not leave us if we get shock while ac current leave us when we get shock
What is the effect of current intensity of 5 mA?
A current intensity of 5 mA (milliamperes) is relatively low and generally safe for most applications, such as in low-power electronic devices or certain medical devices like portable ECGs. However, it can still cause a tingling sensation if it passes through the human body, especially if the skin is wet or if contact is made with sensitive areas. In electrical safety, currents above 10 mA can be more dangerous, potentially leading to muscle contractions or more severe effects. Always handle electrical devices with caution, even at low current levels.
How change a transmitter a millivolts in milliampere for a thermocouple?
To convert a thermocouple's millivolt output to milliamperes, you can use a signal conditioning circuit that includes an operational amplifier configured as a current source. The millivolt signal from the thermocouple is fed into the op-amp, which amplifies the voltage and converts it into a proportional current output, typically using a defined load resistor. The relationship between voltage and current is determined by Ohm's law (I = V/R), where adjusting the resistance will yield the desired current in milliamperes. Additionally, incorporating a temperature reference may help improve accuracy in the conversion process.
how much electrical current to feel tingling sensation?
The amount of electrical current needed to feel a tingling sensation varies among individuals, but it is generally around 1 to 10 milliamperes for most people. Currents above 10 milliamperes can start to become painful and potentially dangerous. It's important to note that individual sensitivity to electrical current can vary widely.
What is 200mA?
50 mA generally stands for 50 milliamperes. A milliampere is a measure used for small electrical currents.
What level of electrical current is safe for the human body?
Generally, electrical currents above 10 milliamperes can be dangerous for the human body, particularly if the current flows through the heart. Currents below this level are less likely to cause harm, but individual factors, such as the path the current takes through the body and the duration of exposure, can also affect safety.
The amount of current that it takes to cause ventricular fibrillation is?
6-30 milliamperes
Generally any current flow above what is considered dangerous?
Generally, any current flow above 10 milliamperes (mA) is considered potentially dangerous to human safety. At this level, it can cause muscle contractions and impair a person's ability to let go of an electrified object. Currents above 100 mA can lead to serious injuries, including ventricular fibrillation, which can be fatal without immediate medical intervention. Always exercise caution around electrical sources to minimize the risk of electric shock.
How much voltage would be needed to produce a current that could be felt?
The voltage needed to produce a current that can be felt varies from person to person, but typically a voltage above 10 milliamperes can be felt by most individuals. Keep in mind that electrical current can be dangerous, and it is not recommended to intentionally expose oneself to electric shocks.
What is 0.005 ampere current the same as?
A current of 0.005 ampere is the same as 5 milliamperes (mA). The conversion is based on the fact that 1 ampere equals 1,000 milliamperes, so multiplying 0.005 by 1,000 gives you 5 mA. This level of current is commonly used in low-power electronic circuits.
What is the current through a 1.5k resistor with voltage of 3V across it?
Two milliamperes. Ohm's law: Current equals voltage divided by resistance.
Which type of current, AC or DC, is more dangerous in terms of electrical safety?
AC current is generally considered more dangerous in terms of electrical safety compared to DC current. This is because AC current can cause muscles to contract involuntarily, making it harder to let go of a live wire, while DC current typically causes a single muscle contraction.
A potentially lethal electric current is on the order of?
A potentially lethal electric current is typically on the order of 100 milliamperes (mA) or higher. Currents as low as 10 mA can be dangerous if they pass through the heart. It's important to remember that even lower currents can cause harm depending on the specific circumstances.
How many miliamber is the one amber?
One amber is equal to 1,000 milliamperes (mA). The milliampere is a subunit of the ampere, which is the standard unit of electric current in the International System of Units (SI). Therefore, to convert amperes to milliamperes, you multiply by 1,000.
What is the relationship between amperes and milliamperes?
Q=it Q = coloumbs I = current T = time
