A 2V battery is connected across AB as shown in the figure. The value of the current supplied by the battery when in one case battery’s positive terminal is connected to A and in other case when positive terminal of battery is connected to B will respectively be :
0.2 A and 0.1 A
0.4 A and 0.2 A
0.1 A and 0.2 A
0.2 A and 0.4 A
As we have learned
P -N junction as diode -
It is a one way device. It offers a low resistance when forward biased and high resistance when reverse biased.
- wherein
R = 0, Forward
R Reverse
In one case
NO current will pass through
I = 2/5 A = 0.4 A
In second case : no current will pass through
I = 2/10 = 0.2 A
Option 1)
0.2 A and 0.1 A
Option 2)
0.4 A and 0.2 A
Option 3)
0.1 A and 0.2 A
Option 4)
0.2 A and 0.4 A
