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).
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
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 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.
