. A semi-conductor diode, whose potential barrier
is 0.7 volt, is connected in series with ammeter A of resistance 0.7 Ω, as shown in the figure. The reading of ammeter is (The resistance of P-N-Diode is 0.7 Ω)
A. 1 A
B. 1/2 A
C. 0.1 A
D. 0 A
Best Answer
Ans: D
Sol: Creation of the potential barrier does not imply that current will flow through the diode
