Solution

The order of current that will generally flow across the PN semiconductor junction diode, when few volts is applied under the forward bias condition, is milli ampere (B).

Here's why:

  1. In a forward bias condition, the P-type semiconductor is connected to the positive terminal of the battery and the N-type semiconductor is connected to the negative terminal. This reduces the barrier potential, allowing current to flow.

  2. The amount of current that flows across the junction depends on the voltage applied and the resistance of the circuit.

  3. For a typical silicon diode, the forward voltage is approximately 0.7 volts. If a few volts (let's say 2 volts for simplicity) are applied, the current flowing through the diode can be calculated using Ohm's law (I = V/R).

  4. The resistance of a diode is not constant and varies with the applied voltage. However, for a silicon diode under forward bias, the resistance is typically in the range of hundreds of ohms.

  5. Using these values in Ohm's law, the current would be in the order of milli amperes.

Therefore, the correct answer is B. milli ampere.
