Question

What is current flowing through resistance of 100 Ohm connected across 2V supply.​

Answer 1

Answer:

Let, D1

​be the diode in series with 50Ω resistance, D2 be the diode in series with 150Ω resistance.  

Diode D1  ​is reversed biased and have infinite resistance hence no current will flow through 50Ω resistance.

Thus, the total current in the circuit is

I=  150+50+100 /6

​ I=0.02 A

As all the resistances are in series, thus we get the current passing through the 100-ohm resistor as 0.02 A.
