In the given circuit, what is the value of the current through the series resistor R2?(a) 9.3 mA(b) 10 mA(c) 0 mA(d) 8.6 mAThe question was asked during an interview.I need to ask this question from Parallel and Series Configuration topic in section Diode Circuit of Analog Circuits

Answer»

The correct ANSWER is (a) 9.3 mA

The explanation: The voltage across the diodes is 0.7 V as they are forward BIASED. Hence, the current through the series resistor = (10-0.7)/1K = 9.3 mA.
