Problem: Use the model for electric current to rank the networks shown below in order according to resistance. Explain your reasoning. 

FREE Expert Solution

Equivalent resistance for resistors in parallel:

1Req=1R1+1R2+...+1Rn

or for 2 resistors:

Req=R1R2R1+R2

Equivalent resistance for resistors in series:

Req=R1+R2+...+Rn

Let's consider each element to have resistance R.

For A, the resistance is R.

For B, the resistors on the right-hand side are in series.
