Series Circuits

• • V=IR
  • I=V/R
  • R=V/I


  What does Ohm's laws state
• • V = voltage in volts(V)
  • I = current in amperes(A)
  • R = resistance in ohm(Ω)
• Add up all the resistance to get Rt(total resistance)


  To find Rt
• 1. I=V/R

  Find the Current

  2. VR1=It x R1

  With the current times one of the resistors to get VR1

  How to find volt drop
• Find

  • Total resistor
  • Total current
  • Total power
  • Volt drop across each resistor
  • Current through each resistor
  • Power dissipated of by each resistor
• When more than one resistor or load is connected end to end, they are considered to be connected on series
• The sum of the voltages dropped across each resistor should give the same value as the source, EMF
