ICE

Hi,

am I doing this calc correct, am I showing calculations correct?


A 10mm main protective bonding conductror of length 15m has a resistance of 0.0275 ohm. Determine the resistance if the length is increased to 25m. Show all calculations.


My Answer: 0.0275/15x25=0.0458325

Cheers

Only thing i`d add to Lenny`s reply is that, if as i assume this is a 3 pointer, they`ll be looking for 3 lines of calc for max marks.

When they say "show all calculations" take the total mick if anything unless you`re really short on time - there again it`s a 2391 so you WILL be short on time :D

You are now entering a time warp where 2.5 hours lasts 13 & 3/4 miinutes
