Question

Assuming that the junction diode is ideal, the current in the arrangement shown in figure is ______.

Options

• 30 mA

• 40 mA

• 20 mA

• 10 mA

Answer 1

Assuming that the junction diode is ideal, the current in the arrangement shown in figure is 20 mA.

Explanation:

In the given circuit, the diode is forward biased, hence the current will flow through it

Now, applying KVL in the above circuit,

+3 - 100i - (+1) = 0

⇒ 3 - 1 = 100l

⇒ i = `2/100` = 0.02 A

i = 20 mA

Hence, the current flow in the circuit is 20 mA.
