Equivalent Resistance

Equivalent Resistance in Parallel Circuits

Open Ended

Determine the equivalent resistance of the cirucit.

Open Ended

Determine the equivalent Resistance of the circuit.

• Unlike series circuits, they have more than one path

• Equivalent Resistance is measured differently.

  1 =   1 + 1 + 1 

  Req   R1  R2  R3
