DC is very very unlikely as it doesn't travel the same as AC does. Also DC typically is at much lower voltages and is easier to ground. DC shocks even at high amps haven't been fatal as the body usually jerks back from the source. AC even a low voltages but with amperage has been known to make people hold onto the voltage source and their muscles spasm as well as their heart leading to death. DC tends to make the more direct path to ground as AC is known to travel outside of it's known physic's laws.
Even though it's the year 2013 ans we can go the moon. Science is still debating if electricity passes to ground or if it passes from the ground. Which may be part of the mystery behind a persons who's foot was wet and yet the AC shot across the person heart and down their arm onto a metal pole. According to physics that's 'impossible'. Voltage supposedly always goes to nearest ground. However- to answer your question CAN DC kill? Answer is yes even though far less likely than a AC source of same voltage and current. The industry clearly states voltage makes little difference unlike current when it comes to fatality which is documented to be fatal at 1/10th of a Amp.
Many people have been killed by direct current. The most frequent deaths caused by direct current are the result of people being struck by the direct current in lightning discharges between rain clouds and the ground Earth. Direct current used in some domestic appliances such as TV's, and in commercial applications including subway and streetcar power systems, is just as dangerous as alternating current, and severe injury or death can result from accidental contact with 'live' electric wires.
in simple terms current kills not voltage.
Batteries produce DC because the potential difference is determined by the chemical reaction inside the battery. This voltage is constant.
There is only 1 type of DC voltage, and that is direct current. In order to better answer your question, you need to be more specific.
A clipping circuit works by the switching action of a diode when it is used in a circuit with a source voltage that changes polarity. In the forward direction, the diode's voltage is added to any dc value that is in series with it. If the source voltage is greater than the dc value at a particular instance, the diode will limit the output to the dc value. Otherwise the output voltage will equal the input voltage.
Yes
unfortunately yes! A DC voltage is potentially more dangerous than an AC voltage due to the fact that ac swings from positive to negative and therefore passing zero volts in the process. If you were say, holding a piece of metal with AC across it you have more chance of letting go than holding the same piece with DC across it. DC is "constantly on" if you like... be careful!
By installing the varialble resistor in the circuit,the constant dc voltage would change .
How do you convert 23 voltage DC to 230 Voltage AC?
luo converter is a new technique adopted for dc to dc voltage lifting(dc voltage boosting)...
DC
DC Voltage
It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.
Many can measure both - Vrms (AC) or DC voltage.
A voltage DC(direct current voltage) is a uni-direction steady voltage. It is the opposite of an analog/alternative voltage which varies in polarity and direction with time.
Batteries produce DC because the potential difference is determined by the chemical reaction inside the battery. This voltage is constant.
first it converts ac to dc as rectifier But the required dc voltage is obtained by taking average of on & off DC input voltage.
Yes, if the fan is designed to work on DC voltage, otherwise no.
A DC-to-DC converter is the general term for a device that changes DC voltage at one level to another.
