No load current, in a transformer for example, is the current necessary for exciting the transformer. If you wish to keep it energized, and you need to keep it energized at full voltage, there is nothing you can do to reduce this other than replace the transformer with one that has lower no load current.
If you are referring to a different piece of equipment, you may need to specify what you are meaning by "no load current".

Why reducing current in circuit?
The current in a circuit is reduced to prevent the circuit from over load.
If you doubled the load resistor in a wheatstone bridge. the load current would not be half as much Why not?
Because by increasing the load resistance, the total circuit resistance is reduced. This means with less resistance, there is more current drawn from the source. Doubling the size of a load resistor increases the load current.
Why SCRs are connected in parallel?
When the load current exceeds the SCR current rating, SCRs are connected in parallel to share the load current. Further the holding currents of the devices should not be so much different that at reduced load current one of the device gets turned-off because of fall of current through it blow its holding current value.
Why is circuit current reduced when a capacitors added to the circuit?
In the case of an a.c. circuit, capacitors oppose current because of their capactive reactance, expressed in ohms. Capacitive reactance is inversely-proportional to the capacitance of the capactor and to the frequency of the supply. So, adding a capacitor is series with an existing load will reduce the load current. On the other hand, adding a capacitor in parallel with an existing load will decrease the load current.

What is meant by regulation or an alternator?
Regulation of an alternator is varying or adjusting the d.c. current flow (excitation current) in the revolving field coil to control the output voltage. When an alternator is subject to varying load conditions, and therefore changing load resistance at the output, the output voltage will vary in response. When output voltage is reduced in response to increased load (reduced output resistance), the "voltage regulator" will respond by increasing the excitation current to increase the voltage output. If load is reduced, the generator will momentarily become over-excited and the ouput voltage will increase. The voltage regulator responds by decreasing excitation current, returning the generator output voltage to its nominal level.
How does load current varies with the load resistance?
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.
What is the no load current of a 90kw motor operating 440V 60Hz?
The no-load current of a motor, such as a 90 kW motor operating at 440V and 60Hz, can vary based on its design and efficiency. Typically, the no-load current for such motors ranges from 10% to 30% of the full-load current. To estimate the no-load current, you can use the formula: No-load current ≈ Full load current × (no-load current percentage). The full-load current can be calculated using the formula: Full Load Current (A) = Power (W) / (Voltage (V) × √3 × Power Factor).
What is the percentage of the no-load current in a transformer to its full load current?
2 to 5% of full load current

What happen to current when paralle resistor added?
For the individual resistor, the current is constant, regardless of any other resister that's attached to it in parallel. The current that results from all the resistors combined decreases as the resistance of one or more of the resistors increases.
