How much does it cost to power a toaster that draws 6 amps of current for 45seconds when plugged into a 120-volt outlet? ( Remember, Centerpoint charges you about $0.16/kWh)

(There are multiple ways to get the correct answer, make sure you can justify with your shown work!)

Predict the appropriate use of parallel or series circuits.

  • burglar alarm

  • want a failure to affect all devices/bulbs

  • want a failure to not affect all devices/bulbs

  • wiring in a house

  • less wires

  • GFCI recepticals

  • need the components to have the same voltage

  • Series Circuit

  • Parallel Circuit
