- Physics
- Electricity
- Mains Electricity
- I't the electricity that is supplied to our homes
- It Powers:
- Lights
- Computers
- Kettles
- Electric Heaters
- The Mains Sockets they power:
- Phone chargers
- Laptops
- Vacumes
- Untitled
- It is supplied by underground cables
- It will then go in to an electricity meter Which measures the amount of electricity used
- It then goes into a consumer unit or fuse box
- The fuse box is a key peace of electrical equipment
- If the current is to large for what ever reason then the fuse will break Saving all your electrical goods
- This works because when electricity has a high current it get's quite hot so if you get the type and thickness of wire correct it will melt when the current gets to high breaking the circuit
- If the current is to large for what ever reason then the fuse will break Saving all your electrical goods
- The fuse box is a key peace of electrical equipment
- All Electrics are wired in a certain way In England
- It has a live wire which carries the current and this wire is the one with the fuse attached
- It has a neutral wire which the current exits through (to complete a circuit)
- How ever in England we have a Earth wire which is a safety feature
- If an appliance has a metal casing then an earth wire is needed to stop someone dying in a fault
- If the live wire touches the metal casing then a person does they will get a SHOCK
- When the live wire touches the casing then the current will flow down the low resistance Earth wire increasing the current and so melting the fuse
- If the live wire touches the metal casing then a person does they will get a SHOCK
- If an appliance has a metal casing then an earth wire is needed to stop someone dying in a fault
- The Electricity leaves the fuse box and ends up in the ring circuit
- The ring circuit is where we can access the electricity from through the mains
- It then goes into a consumer unit or fuse box
- It will then go in to an electricity meter Which measures the amount of electricity used
- It Powers:
- I't the electricity that is supplied to our homes
- Mains Electricity
- Heat
- Heat Loss
- Heat can be lost by evaporation
- Evaporation is when the hot or vibrating molecules evaporate off meaning that there aren't any hot molecules left just the slow vibrating cold ones
- Heat can be lost by evaporation
- Heat Loss
- Electricity
