Slide 1 - Tekstslide

Lesson goals:
  • Calculate the resistance in a parallel circuit
  • Explain how the current works in a parallel circuit
  • Explain how the voltage works in a parallel circuit
  • Use the law of ohm to calculate unknown values in a parallel circuit

Slide 2 - Tekstslide

More resistances in parallel...
Rtot1=R11+R21+R31+...
The more resistors you connect in parallel, the smaller the total resistance.

Slide 7 - Tekstslide

Current in a parallel circuit 
The current divides 
into the branches of 
the parallel circuit
THEREFORE


Itot=I1+I2+I3+...
