For the circuit shown in the figure, the maximum output voltage V o is

Options

  1. A0   V
  2. B5   V
  3. C10   V
  4. D5 2   V

Correct answer

B. 5   V

Step-by-step solution

We are given a circuit and an input cycle We need to find the maximum output voltage, V 0 For the positive half cycle of input, the resulting network is shown in figure (B), Here Diode D 1 is in OFF state and Diode D 2 , is in ON state. The circuit has been redrawn simpler in figure C . From the figure C , Equivalent resistance, R e q = R 1 × R 2 R 1 + R 2 ⇒ R e q = 4 × 2 4 + 2 = 4 3   kΩ The maximum current flowing through the source i m a x = V R (Using Ohm's law) ⇒ i m a x = 1
