Electricity

• This is a LDR

  
• This is a thermistor

  
• This is an ammeter

  
• This is a voltmeter

  
• This is a fuse

  
• This is a bulb

  
• This is a LED

  
• This is a variable resistor

  
• This is a resistor

  
• This is a diode

  
• This is a battery

  
• This is a cell

  
• This is a switch

  
• What is a series circuit? Circuit flows through single closed loop.
• What is a parallel circuit? Current flows through two or more branches before combining again
• thermistor -as temperature increases resistance decreases
• LDR- as light intensity increases resistance decreases
• Current = charge flow ÷ time

  ( I = Q ÷ T )
• Current is measured in amps
• Charge flow is measured in coulombs
• The neutral wire is blue
• The live wire is brown
• The earth wire is green and yellow
• Neutral wire is to the left
• Earth wire is on the middle
• Live wire is on the right
• A fuse melts when current gets too high
• Earth and neutral wire are 0 V
• Live wire is 230 V
