Solution


Q.

Refer to the circuit diagram given in the figure, which of the following observations are correct             

A. Total resistance of circuit is 6 Ω.

B. Current in Ammeter is 1 A.

C. Potential across AB is 4 Volts.

D. Potential across CD is 4 Volts.

E. Total resistance of the circuit is 8 Ω.

Choose the correct answer from the options given below:                   [2025]
1 A, B and D only  
2 A, C and D only  
3 B, C and E only
