# Rodents and flooding

Thinking of renting a 1st floor flat, there is a ground floor and a basement as well. Speaking with the neighbour, he says they have a problem with rats from the river at the back. When I viewed the basement, there was a dead rat which had died from eating bait. My question is this, the first floor is up a flight of steps, can rats climb these?

Secondly, with the recent floods in Yorkshire, how is it people were not killed when the water touched the mains electrical sockets in everyone's house just out of interest

Sorry for the 'mythbusters'

Dunno about electricity, but rats can certainly climb stairs. They'd be more likely to get into your flat through the drains though. I wouldn't worry about it too much though, apparently in this country you're never more than 10 metres away from a rat

I think your electricity problem would be solved by fuses. Probably wrong though.

Rats climb stairs easily.

Electrickery works through trip switches that cut the power to stop you dying.

Cool! Thanks

The whole of the body of water is simply not going to rise to 240v above ground, a lot of parts of it afterall in contact with the earth which is defined at being 0v, water is a complex 'net' of resistances and there will be places where a current is passing through part of the 'net' to the ground setting up a voltage gradient of between 240v and 0v in respect to the ground. It'll also allow tracking between conductors in accessories and where the circuit is protected by an RCD I'd expect this to open, but where the only protective device is an overcurrent device its very unlikly you'd convince enough current to flow to open it.

If you were to touch the water near a flooded electricial point is more than possible that you would get a shock, how severe it would be would depend on many factors such as the voltage at that point, the resistance of the path through the water, your skin resistance (lower when wet!), your resistance to ground.

The saving grace is the water near electrical accesories is likely to be less pure than that around it, due to dust and plaster particles, etc which means that the majority of the current flow from that which goes astray is going to quite localised, and the fact that the water as a whole isn't going to be pure anyway (if you drop an applicance in the bath, its more likely that you'll electrocute yourself if the water is reasonably pure than if its not... you don't want to have a lower resistance than the water that surrounds you as such would make you you the 'prefered path' for the bigger potion of the current flow)

popular belief is that electricity takes the easiest path, this isn't strictly true, the easier the path in comparison to the others the more electricity takes, but if you have two paths, it would be wrong to assume that nothing will flow through the 'harder' one (it actually devides in the ratio of the reciprocal of the impedances of the paths offered)

Sorry... I have gone on a bit
