What is the percentage of the no-load current in a transformer to its full load current?
2 to 5% of full load current
The current load of a trnsformer is the current drawn by the?
Load!
What is the formula to calculate the overload setting for a star delta starter?
Full load current ofthe motor x 0.58
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 will happen when we change value of load resistance in transformer?
When the value of the load resistance in a transformer is changed, it will affect the current flowing through the circuit. Increasing the load resistance will decrease the current, while decreasing the load resistance will increase the current. This change in current will in turn affect the voltage across the load and the efficiency of the transformer.
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.
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
The current load of a transformer is the current drawn by the?
load
The current load of a trnsformer is the current drawn by the?
Load!
Why the waveform of no load current is not sinusoidal?
No load current is mostly inductive, hence the load current may not be a sine wave
What is the formula to calculate the overload setting for a star delta starter?
Full load current ofthe motor x 0.58
