How much does it cost to power an induction stove that draws 6 amps of current for 32minutes and 45 seconds when plugged into a 240-volt outlet? ( Remember, Centerpoint charges you about $0.16/kWh)
(There are multiple ways to get the correct answer, justify with your shown work!)

8

Predict the appropriate use of parallel or series circuits.

  • less wires
  • GFCI recepticals
  • want a failure to not affect all devices/bulbs
  • burglar alarm
  • want a failure to affect all devices/bulbs
  • need the components to have the same voltage
  • Series Circuit
  • Parallel Circuit
6

Match the left definition with the appropriate term on the right.

  • measure of the electrical push through a wire
  • = V/I
  • = V/R
  • measure of how much electricity is being pushed
  • measure of the resistance to electrical flow
  • = I*R
  • Ohms
  • Current
  • Volts
