the cable sizes are...:
lighting=1mm-1.5mm
sockets-boiler controls=2.5mm
cooker=6mm
shower=10mm (can vary depending on the showers output)
earthing conductor of 10mm
earth bonding conductors of 6mm
25mm tailings (you're supply cables from the meter)
The sizes also depend on weather or not the cable is wired in old colours (i have only entered the new cable sizes)
circuits used are...:
ring main.
radial=only used if there are limited sockets being installed on a circuit.
lighting is just 1 cable going out and spreading to each light and switch (upstairs and downstairs lighting should be on a separate mcb)
cooker-1 cable going out of mcb.
shower-1 cable going out of mcb.
I hope this information helps as i don't fully understand what you are wanting to know from you're question. If you need any more help please let me know, or anyone else for that matter.

The electrical lines to a typical house in the UK are 230 V 50 Hz.
The power runs through electrical circuits that are mapped out by the city.
All electric house
The effects of electrical shock are many. Some examples... * Tingling * Spasm * Pain * Burned flesh * Fire * Death
No, because household electrical systems are only comprised of a single phase.
CU this is the right answer by killerjo
They are not grounded therefore can not carry an electrical charge.
All of the electrical outlets in a house are in parallel across the electric company's AC service entry into the house.
It is possible that the electrical wirings are grounded. You'll probably need to get an auto-electrician to take a look at it.
by its wirings...... ^_^
This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask the answer of. Earn your diploma.
The simple answer is, "Gravity". Gravity pulls the wires down just as it pulls everything else down. The wires can only be pulled with a maximum tension, and all the while gravity is pulling down.

It is an electrical insulator. Most stones are examples.
Good examples of electrical resistance would be an electrical baseboard heater, electric hot water tank and an electrical kettle. All of these devices use a resistive element to create heat.
Some examples of electrical software include: AUTOCAD, altium designer, wintac, promis-e, solutions electrical software, ETAP, Amtech, and smart draw.
