    Quick question:

    When I attempt the equivalent resistance problem, I'm having hard time redrawing the circuit after finding some resistors in series or parallel.

    For example, the problem asks to find the resistance with respect to terminal F and J.

    By drawing the node I see that
    (2.7+3.9) || 4.3

    this involved terminal G, L, and K... which I could redraw the resistor (equivalent resistor) between any combination.

    Also this cause some terminals to be disappear...

    any tips on redrawing the circuit after finding the series/parallel resistors?

    So, key is to redraw in the beginning? and then work from there?

    It's probably a matter of personal preference. It takes some practice to be able to visualize this 'process'. Some people are good at this - or have a natural bent to visualization. Not my strong point.

    I see, it is very hard for me to see the connections as well... need more practice I guess. Thanks for the help anyway! appreciated!
