Q.
The current through the battery shown in the circuit is
NTA AbhyasNTA Abhyas 2020Semiconductor Electronics: Materials Devices and Simple Circuits
Solution:
Since diode D1 is reverse biased, therefore it will act like an open circuit.
Effective resistance of the circuit is R=4+2=6Ω .
Current in the circuit is I=E/R=12/6= 2 A.
