What is the meter reading for a forward biased diode is likely to be when using the diode test range of a digital multimeter?

A: Nobody can answer that. It depends on the diode, battery on the meter, scale of the meter. It should never read zero or close to zero ohms and reversing the lead it should just be close to open but it may read some hi k ohms. A meter test is just to find shorted diodes and extremely leaking diode.

What are the characteristics of forward bias?
characteristics of forward biased
What if a semiconductor diode is being tested using a digital multimeter and the resistance of the diode is 10 ohms in both forward and reverse-biased conditions is the diode shorted or opened?
The diode is neither shorted nor open. It is a zener diode and it is conducting in both directions. If it were truly shorted, it would read closer to zero ohms in both directions.
What does LED do in a circuit?
light up when forward biased
How is a non-conducting diode biased?
A nonconducting diode is biased in the reversed direction (reverse polarization).
Does the diffusion capacitance exit in forward biased diode?
Yes
What happen of a a diode When forward-biased?
when a diode is forward biased it conducts current

Approximate voltage across the forward-biased base emitter?
The approximate voltage across the forward-biased base-emitter junction is 0.7 volts.

How much voltage is there across a silicon diode when it is forward biased?
0.7 The voltage across a silicon diode when it is forward biased should be greater than or equal (>=) 0.7volts.
Is less than or greater than zero external voltage applied on diode when you deal with forward biased?
A forward-biased diode has a positive DC on its anode with respect to its cathode.
Is light emitting diodes emit visible light when forward biased?
It depends on the particular LED. Some of them emit infrared light. But, yes, emission occurs when forward-biased.
How is a non-conducting diode biased?
A nonconducting diode is biased in the reversed direction (reverse polarization).
Zener diode with its forward biase?
acts like a normal diode in forward biased condition
What is forward biased p-n junction?
A conducting junction.
Does the diffusion capacitance exit in forward biased diode?
Yes
