V1=100+400400×12 V=54×12=548 V
here, V1>Vz,(Vz= Zener Voltage ) So, Zener breakdown will be take place So, voltage across 400Ω will be 4 V
I=4004 A=100 A1=10 mA
In the following circuit, the reading of the ammeter will be (Take Zener breakdown voltage =4 ~V) JEE Main 2025 Physics, Semiconductors — question…
