  1. Electricity Static Electricity AC & DC Currents Series & Parallel Circuits Ohm’s Law

  2. carpet doorknob Static Electricity When something has a build up of electrons creating an imbalance in charges resulting negative static charge. For extra understanding click here Opposites______. Like charges ______. attract repel Examples: hair balloons lightning

  3. AC & DC Currents Current = the flow or movement of electrons. Definition The source Only goes D.C. current Both ways (+ to -) A.C. current

  4. ACvsDC Sort out the devices into their correct power supply 8. 1. 4. 6. 2. 9. 5. 7. 3.

  5. +- Circuits Electricity travels from positive to negative charges. Opposites attract each other. When electricity is run through a wire from a source and back again it is called a circuit.

  6. +- What happens if this one goes out? What happens if this one goes out? Series Circuits They all go out because the circuit is broken.

  7. +- What happens if this one goes out? Parallel Circuit The others stay lit because the circuit isn’t broken.

  8. Ohm’s Law The relationship between current, resistance, and voltage. What is it? Measured by Fill in the chart Current Flow of electrons AMPS Slows flow of electricity Resistance Ohm’s Voltage Electric “push” Volts

  9. Ohm’s Law cont. Voltage = current x resistance c r V = The current is 25 amps and the wire resistance is 5 ohm’s what is the Voltage needed to run the motor? V= 25 x 5 V= 125 volts

  10. Electromagnets A magnet can be temporarily made by running electricity through a coil of wire wrapped around a piece of iron.

  11. Motorcycle Fan Washer & Dryer Drill Lawnmower Car Doorbell Clock Pencil Sharpener Everyday Electromagnets Pick the objects below that have an electromagnetic motor?

  12. Moving Magnets make Electricity When a Magnet is spun inside another magnet electricity is generated.
