    Find effective resistance
    An electric bell takes a current of 0.2A from a battery of two cells connected in series.each cell has an emf of 1.5V and an internal resistance of 1.0ohms.calculate the effective resistance of the bell and what current would the bell take if the cells were arranged in parallel.

    e.r is 2 ohm
    And in parallel also the same will be the current (voltage received by cells is 1.7 volt)... plsss cross check

Find the resistance of CD (Rcd) [ 7 Answers ]

in the picture you can what I did till I stuck. NO.1 is the source, and NO.2 is after I found the equivalent resistance R-5,6,7 (which is in parallel). but now I think R2 and R1 is also parallel but I am not sure. all I know that is the final answer should be Rcd=3-ohm thanks.
