Physics Question from JEE Main 2025 · 23 January, Shift 1

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

Circuit diagram: a 6 V battery, an ammeter A in the top branch at point C, a 4 ohm resistor from C down to D, a diode from D pointing to A in series with a 4 ohm resistor from A down to B, and a third 4 ohm resistor from D down to the bottom rail; points A, B, C and D are marked.

A. Total resistance of circuit is 6 Ω6 \, \Omega B. Current in Ammeter is 1 A1 \, \text{A} C. Potential across AB is 4 Volts4 \, \text{Volts} D. Potential across CD is 4 Volts4 \, \text{Volts} E. Total resistance of the circuit is 8 Ω8 \, \Omega
