Electric Current!

  1. Mar 19, 2008 #1

    Above is a battery connected through a circuit. We have to find the Total Resistance (R t) by solving in terms of R.

    I'm really confused because I'm not sure what's parallel or in series.

    Please, help!

    Well, for this type of circuit, you need to have a test current of 1A. Figure out the total voltage in the circuit using Kirchhoff's current law, and then find the total resistance by using R = V/I.

    It's quite a hard circuit analysis question, in my opinion.

    The one you have there is called a bridge circuit. To calculate total resistance, you must substitute the given resistor circuit with an equivalent one.
