- Mains Electricty
- AC Current
- Discovered by Tesla
- The most effiecient
- This is because it can be transformed to a different voltage to increase efficientcy
- Alternating Current
- On an oscilloscope it would show a wave
- This is because the current is constantly changing direction
- DC Current
- Discovered by Edison
- Major Downside
- It can't be transformed, so only has certain uses
- Power comes from a cell
- usually a battery
- Direct Current
- On an oscilloscope the line would be straight
- This is because the current only travels in one direction
- Plugs
- Live Wire
- Usually Brown in colour
- Earth Wire
- Usually Green and Yellow in colour
- The earth plug is longer as it unlocks a gate so that mains is then supplied
- Neutral Wire
- Usually Blue in colour
- Live Wire
- Equations
- Power (W)
- Energy Transformed (j) / Time (s)
- Electrical Power
- Current (A) x Potential Difference (V)
- Potential Difference (V)
- Current (I) x Resistance (R)
- Power (W)
- AC Current
