Five equal resistances each ' 2 R ' are connected as shown in figure. A battery of ' V ' volts connected between A and B. Then current through FC is
Options
- AV 4 R
- BV 8 R
- CV R
- DV 2 R
Correct answer
A. V 4 R
Step-by-step solution
The circuit diagram can be redrawn as R _ FC R _ FD = 2 R 2 R =1, R _ CE R _ DE = 2 R 2 R =1 R _ FC R _ FD = R _ CE R _ DE The circuit is a balanced Wheatstone bridge. The current through FC is I_ F C = R 2 R+2 R = V 4 R
