either one, neither one
Current is what is can hurt or kill you.
It is a function of the resistance put across those voltages
no both are equal
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
given a balance three phase, three wires system with star-connected load for which lime voltage is 230v and the impedance of each phase is (6+j8)ohm. find the line current and power absorbed by each phase.
its less then the total current
It's a decision based on efficiency of power transmission.
one note on Dc, and AC voltages? sure A DC is a Direct current, which means more accuracy and power. The device using DC power will maintain its action for longer with more accuracy. Whilst AC is commonly used for lights and other unimportant devices. That's the first note i could come up with. ------------------------ DC is direct current which as the name implies, the electrons (of the current) flow in ONE direction. AC is alternating current, which as the name implies, the current alternates and has a "useable/definable" frequency. AC has no definite terminal (Positive or negative) as the direction of the current always changes. This frequent switching can be seen as a sine wave.
To not hurt yourself and to prevent with devices that redirect current or break circuits
Alternating current is not necessairly low voltage, on the controrary AC is more oftenly used for when high voltage is needed. Most power distribution systems (extremely high voltages) use AC because AC is easier to transform to high voltages (using the aptly named transformer). High voltage is needed for power distribution to decreases losses due to transmission.
Kirchoffs's current law states that the sum of all the currents flowing out of any point is equal to zero. In other words, the current flowing in is equal to the current flowing out.In the case of a parallel circuit, this means that if a single current branches into two or more parallel branches, then the sum of the currents in the parallel branches must be equal to the original current before it branched.
Both will kill you easily ;) But medium/high voltage, high current DC is generally considered 'more dangerous' as it tends to make people clamp onto the cable rather than being thrown away from it, so fault current is suffered for longer as a result. Hope this helps. Paul. ANSWER : NOT TRUE VOLTAGE DOES NOT KILL current however will even a 'D' cell can kill you [able to deliver 2 amps] Now which is more dangerous DC for sure it is continuous AC WILL PASS TROUGH ZERO AT TIMES ENOUGH MAYBE TO DISCONNECT
