How do I solve the equivalent resistance of this circuit?
Redraw the circuit.
Start by putting the node labels &quot;A&quot; &amp; &quot;B&quot; on all nodes that connect directly to the input terminals.
Then draw the circuit with all of the resistors parallel to each other where possible.  Obviously, have all of the node &quot;A&quot; ends of the resistors at the top (or bottom) and all of the node &quot;B&quot; ends of the resistors at the opposite end.
The solution should be fairly obvious when you have done this.
