Web21 aug. 2024 · A transient simulation could also be used to analyze responses of DC or steady-state AC signals to get a result similar to those dedicated simulations types, however it will likely have lower accuracy since it is a more general-purpose simulation (especially worse accuracy for AC). WebRealistically (statistically) speaking, AC is more dangerous that DC. This comes from the fact that 120/240v AC is the voltage that we are most likely to encounter - which can kill … WebYes. DC current will travel through the entirety of the wire -- AC current will tend to move on the outside of the conductor (see Skin Effect). This will cause slightly more ohmic heating in AC than in DC. That's why AC wire is usually stranded while DC wire is usually solid -- more strands = more surface area. interstitial disease nephritis treatment
