-
If the live wire touches the outer casing the earth wire profides a safe place for the energy to flow without causing a shock

National grid
Energy is shared to consumers through the national grid at a very high voltage to reduce energy loss
the fuel is burned to boil water to make steam
the steam makes a turbine spin
the spinning turbine turns a generator which produces electricity
the electricity goes to the transformers to produce the correct voltage

Beta
Fast moving electrons
When a beta particle is released the atomic mass number remains unchanged but the atomic changes to an increase in one
-
-
-
When an unstable nucleus decays it gives out either Alpha,Beta or Gamma particles
