Consider a circuit consisting of a capacitor ( 20 F), resistor ( 100 ) and two identical diodes as shown in figure. The resistance of diode under forward biasing condition is 10 . The time constant of the circuit is 10⁻³ s. The value of is _____

Options

  1. A2.2
  2. B2.0
  3. C2.1
  4. D2.4

Correct answer

A. 2.2

Step-by-step solution

From the given circuit diagram, the battery is connected such that its positive terminal is upwards. This means the current will flow in the clockwise direction during the charging of the capacitor. In the parallel combination of the two diodes, the left diode is pointing downwards (in the direction of the current) and will be forward-biased. The right diode is pointing upwards (opposite to the current) and will be reverse-biased. The reverse-biased diode offers infinite resistance and acts as an open circuit. The
