Can a resistance be used in the circuit instead of diode?

No. A resister is not a replacement component for a diode. A resister is passive and allows current to flow through in in both directions. A diode is a single semiconductor junction that only allow current to flow in one direction.

Does electric current remain constant in a circuit?

No it depends on voltage and circuit resistance and other physical parameter which affect the properties of component used in circuitry like - temperature pressure humidity light(in light sensitive circuit- LDR photo diode,photo transistor,) and other.

When does the diode not allowed to flow the current?

A diode is a one-way gate for electrical current to flow through. You must have the right size diode for the amount of current that will be used in your circuit. The stripe on the diode is your output end. That is, the current must enter your diode at the non-stripe end and leave at the end with the stripe. This coincides with the diode symbol used on your schematic. If your diode is in backwards, the circuit will not work as the gate in the diode will block the current just the way it should.

What is the purposed of resistance in the circuit?

Resistance is generally used to control the flow of amount of current in the circuit.

Why resistance use in silicon diode characteristics?

Resistance is used in characterizing silicon diodes, or any component for that matter, because the equivalent resistance in a certain condition tells you what the circuit will do in that condition. It is true that a diode is not a resistor, but it has an equivalent resistance at each point on it operating curve. Let take three points, for example... With one ampere of current, the forward voltage might be 0.68 volts. That corresponds, using Ohm's law, to a resistance of 0.68 ohms. With ten amperes of current, the forward voltage might be 1.15 volts. That corresponds to a resistance of 0.115 ohms. With 25 amperes of current, the forward voltage might be 1.7 voltage. That corresponds to a resistance of 0.068 ohms. You can obtain the forward resistance curve from the manufacturer's data sheet. Even if there is only a voltage versus current curve, you can calculate resistance using Ohm's law. You need to know the resistance curve in order to design the circuit that uses the diode. In high performance situations, such as in large power supplies, the resistance of the diode may well be critical, and would therefore be a factor in selecting which diode amongst several choices to choose.

Is zener diode a voltage amplifier or currentlimitig circuit or osilator circuit?

The zener diode is neither a voltage amplifier nor a current limiting device but can be used in oscillator circuits to supply a constant output voltage.
