How much of ampere can kill?
Milliamps are dangerous Less 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. possibily 1-2Amp/s can make your heart stop. and kill you. Not the amount of voltage
How much curretn is in a circuit that includes a 9- volt battery and bulb with a resistance of 12 ohms?
Current, I is equal to V (voltage) divided by R (resistance); Hence: I=V/R = 9V/200 ohms: I = 0.045 Amps, or 45ma (milliamps).
Is 4 kv and 30 ma be lethal from dry hand to hand?
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.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
What is current gain and voltage gain?
Current gain is the ratio of output current divided by input current. Voltage gain is the ratio of output voltage divided by input voltage. Nothing more complicated than that.
2 volts divided by 100 kOhms equals how many milliamps?
2 volts across 100 kOhms produces 0.02 milliamps (or 20 microamps) of current. Ohm's law: Voltage = Amperes * Ohms, so Amperes = Voltage / Ohms.
How many ma equal to 3 volts?
The relationship between current (measured in milliamps, or mA) and voltage (measured in volts) is determined by Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). Without the resistance value, we cannot directly convert 3 volts to milliamps.
If the current is 33 milliamps and the resistance is750 ohms what is the voltage?
24.8 Volts
5.1v is the Voltage, You need to also look at what the Amperage rating is on the charger. 500ma, 1000ma, etc. How many Milliamps?
5.1v is the Voltage, You need to also look at what the Amperage rating is on the charger. 500ma, 1000ma, etc. How many Milliamps?
8 volts divided by 40 milliamps equals?
0.2
What is the human withstanding capacity towards voltage in ac and in dc?
Milliamp 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 can kill amperage or voltage?
Amperage and voltage can be dangerous if they exceed safe levels for a particular device or circuit. Excessive amperage can cause overheating and damage to electrical components, while high voltage can lead to electric shock and electrical fires. Proper circuit protection devices, such as fuses and circuit breakers, are used to prevent excessive amperage and voltage from causing harm.
How many milliamps equal one watt?
To calculate the current in milliamps (mA) from power in watts (W) and voltage in volts (V), use the formula: Current (I) in amps = Power (P) in watts / Voltage (V) in volts. You can convert the result from amperes to milliamperes by multiplying by 1000 since 1 ampere = 1000 milliamperes.
How much of ampere can kill?

How many milliamps are in 12 volt dc - 2watts dc?
To calculate the current (in milliamps), you can use the formula: Current (in mA) = Power (in watts) / Voltage (in volts). In this case, Current = 2 watts / 12 volts = 0.167 amps. To convert this to milliamps, multiply by 1000: 0.167 amps * 1000 = 167 mA. Therefore, there are 167 milliamps in a 12V DC, 2W DC circuit.
How much curretn is in a circuit that includes a 9- volt battery and bulb with a resistance of 12 ohms?
Current, I is equal to V (voltage) divided by R (resistance); Hence: I=V/R = 9V/200 ohms: I = 0.045 Amps, or 45ma (milliamps).
What is deadlier volts or amps?
The formula for amperage is Amps = Voltage / Resistance. As the voltage become higher so does the current that can flow through your body if you short across an electric potential. Remember that 1 amp is equal to 1000 mA. The following list is the tolerances that the body can stand. 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 milliamps, Paralysis of breathing resulting in death.
