I have a power cable for my computer that got slightly chewed and i was wondering does that effect the power.im just wanting to know if it will have less power or will it work the same and as far as i know none of the wires where hurt just the rubber around them.
replace your cable as its now a fire and shock risk
It will work if the wires are undamaged. But they will have been kinked when the cable got chewed. The cable is now dangerous, if the wires are pinched you may get a hot spot, melt the insulation and fire/shock hazard. Turn it off and replace the cable.
