Five equal resistances each of resistance R are connected as shown in the figure. A battery of V volts is connected between A and B. The current flowing in AFCEB will be [CBSE PMT 2004]

A)         \[\frac{3V}{R}\]

B)         \[\frac{V}{R}\]             

C)         \[\frac{V}{2R}\]

D)         \[\frac{2V}{R}\]

Correct Answer: B

Solution :

                                         The given circuit can be redrawn as follows Equivalent resistance between A and B is R and current \[i=\frac{V}{R}\]
