Load current refers to the current flowing through a load in an electrical circuit, which is the part of the circuit that consumes electrical power. It can be calculated using Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). The formula is expressed as ( I = \frac{V}{R} ), where ( I ) is the load current in amperes, ( V ) is the voltage across the load in volts, and ( R ) is the resistance of the load in ohms.

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 is the formula to calculate the overload setting for a star delta starter?

What is the difference between no load current and no load voltage?
What does the question refer to? Induction motors? Transformers? For transformers, the no-load voltage is the voltage -- across the secondary or primary -- when there is no load attached to the secondary, that is, when there is no current in the secondary. No-load current really only makes sense when talking about a motor, because current is flowing in the device even when it's not under load. A rule of thumb is the no-load current is about a third to one half the full-load current.

What is the formula of load calculation?
There are various formula of load calculation. Power equals current multiplied by the voltage. Power can also be computed by multiplying the resistance by the square of the current.
What is the formula for calculating the full load current of 3kW motor?
The formula you are looking for is I = Watts/ Voltage, I = 3000/voltage.
How an electric iron works?
Basically you apply a voltage to a load (the iron's heating element) which induces a current. The current through the load generates heat according to the formula Power = Current^2 * Resistance.
What is the formula to calculate secondary current?
The secondary current is calculated by dividing the secondary current by the impedance of the load. This value shouldn't exceed the secondary-winding's rated current except for short periods of time.
How much load current of an ac?
Load current is simply the name given to the current drawn by a load from its supply. In the case of a d.c. circuit, this is determined by dividing the supply voltage by the resistance of the load; in the case of an a.c. circuit, it is determined by dividing the supply voltage by the impedance of the load.
What is the formula of active power?
For a single-phase system, active (or 'true') power is the product of the supply voltage, the load current, and the power factor of the load.
How do you calculate no-load current and load current?
Full load current can be calculated by the formula given below: P=SQUARE ROOT OF 3*V*I*POWER FACTOR P=1.732*V*I*PF suppose 3 kw motor three phase voltage assuming .85 power factor and 415 volt full load current will be 3*1000=1.732*415*I*.85 I=4.9 ampere(full load ampere)
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 percentage of the no-load current in a transformer to its full load current?
2 to 5% of full load current
