Question

Two ideal diodes are connected to a 5 V supply with 10 Ω and 20 Ω branches as shown. Find the supply current.

G1 Physics · Accepted Answer

Use diode polarity to identify the conducting branch in the given figure. The forward branch has resistance 10 Ω, while the other is blocked. The total current is I = 5 V/10 Ω = 0.5 A. Final answer: Option D.
