  For the circuit shown in the given figure, What is the value of (a) current through  resistor? (b) potential   difference   across   resistor?

Answer:

                  Let the current through the circuit be I which is divided into and in the arms AB and CD respectively, then In the arm AB, the total resistance is                                  and the total resistance in the arm CD is             (a) Current in resistor Current through CD is(1) (b) Potential difference across resistor is                   (1)
