'Ohm's Law'

• Voltage


  The potential difference in energy between two points in a circuit and is measure in volts (V)
• Current:


  The rate of flow of electrons in a circuit, carrying energy, and is measured in Amps (A)
• Resistance


  Resistance is the opposition to current flow in an electrical circuit, converting energy to heat it is measured in Ohms (Ω)
• Series circuit


  • Unbranching, continuous path for electricity to flow
  • Only one path to follow
  • Voltage slowly drops throughout the circuit
• Parallel Circuit


  • A split path with multiple routes
  • Voltage is the same across each component of the parallel circuit.
• Volts (V)(unit of measurement)

  Voltage (V)
• Resistance (R)(unit of measurement)


  Ohms (Ω)
• Current (I)(unit of measurement)

  Amps (A)
• resistance


  slowing down the current
• resistor


  An electrical device that resists the flow of electrical current
• current


  the number of electrons passing a point in a certain amount of time
• Direct Current (DC)


  Electric current that flows in only one direction
• Alternating Current (AC)


  electric current that alternates direction periodically
• load


  the appliance a circuit is powering
• insulator


  A material in which electrons are not able to move easily
• conductor


  A material that allows heat and electricity to pass through it.
• voltage


  potential energy of flowing electrons
• Ohm's Law


  the current in a circuit equals the voltage difference divided by the resistance
• ammeter


  A device used to measure current in a circuit
• voltmeter


  A device used to measure voltage, or electrical potential energy difference

• light bulb symbol

  
• wire symbol

  
• ammeter symbol

  
• voltmeter symbol

  
• resistor symbol

  
• switch symbol

  
• series circuit


  A circuit in which all parts are connected end to end to provide a single path of current.

  
• parallel circuit


  A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit.
