cable resistance

Tuesday 24 July 2018

Here's an interesting one. I got this compressor for painting my car, as it happens I'm not going to use it. All the mixing of chemicals put me off, too much like chemistry. Anyway it has other uses like blowing dust away, sand blasting and blowing up tyres. My garage is some distance from the house so I have to use two connected extension cables to connect to the mains electricity. Everything seems to work OK but the other day I used the compressor to sandblast a grill and connected it directly to the house socket. Everytime I switched it on it tripped the switch. It seems that the extra resistance of the extension leads reduce the current enough to stop this happening in the garage. Maybe all my electrical appliances are running under power? Might explain why my drill is so weak.
