Determine Vo and ID for the networks of Fig. 2.156.FIG. 2.156

The diode in ON condition can be represented by adding a additional voltage as shown in Figure 2.

Apply Kirchhoff’s Voltage Law around the loop as shown in Figure 2.

Hence, output voltage is .

Determine the value of the current .

Substitute for .

Hence, the diode current is

(b)

Refer to Figure 2.156(b) from the text book.

The diode in the circuit is forward biased.

The diode in ON condition can be represented by adding a additional voltage as shown in Figure 3.

Use the Ohm’s law to calculate the current, .

Hence, the diode current is .

Calculate the output voltage.

Hence, the output voltage is .
