What is the equivalent resistance of the circuit?

5.5Ω

Explanation:

The circuit diagram shown is a parallel arrangement. To solve this problem for the equivalent resistance,

  R1  = 10Ω

  R2  = 20Ω

 R3 = 30Ω  

For circuits in parallel, equivalent resistance is ;

      =  

 Now insert the parameters and solve;

     =  

      =  

      =  

    Rt  = 5.5Ω
