For the circuit shown in figure. The point F is grounded. Which of the following is wrong statement ?

Options

A. D is at 5 V
B. E is at zero potential
C. The current in the circuit will be 0.5 A
D. None of the above

Answer

A

Explanation

Effective emf of circuit =10-3=7 V
Total resistance of circuit `=2+5+3+4=14 Omega`
Current `l=7//14=0.5 A`
Potential difference between A and D `=0.5xx10=5A`
Potential at D=10-5=5 V
Potential at E=5-3=2 V
Hence, E cannot be at zero potential, as there is a potential drop at E.
