480 transformer to 120 ac current what is the kva on transfomer?
The kVA rating will be listed on the transformer's nameplate, which is usually on the front of the transformer. The 480v to 120v is irrelevant, because many transformers with different kVA ratings convert 480 volts to 120 volts. The kVA ratings can be different and thus affect the rated current through the transformer.
What is the affect of core saturation upon turns ratio of a transformer?
Electrical Engineering
Is it the value of input voltage equal the value of output voltage?
No. There are several factors that may affect the output voltage. For instance: Resistors, Transformer, Voltage regulators and others that can control the output voltage to a certain level.
Why is electrical resistivity important to a design engineer?
electrical resistance increases current flow decreases.so to know the current flow in the network ,electrical resistance is required.AnswerResistivity is important, because it is one of the three factors that affect the resistance of a material. The other factors are the length and cross-sectional area of the material.
How frequency affect the performance of a transformer?
Transformers are designed for a specific application. frequency IS A MAJOR FACTOR THAT GOES INTO THE DESIGN.
What will happen when we change value of load resistance in transformer?
The secondary load current will change. This, in turn, will cause the primary current to change (the primary current being the phasor sum of the [IS (Np/Ns)] and the primary current (Io).
What happens when frequency is increased of transformer?
When the frequency of a transformer is increased, the core losses of the transformer increase due to increased eddy current losses and hysteresis losses. This results in a rise in temperature of the transformer. Additionally, higher frequency can affect the impedance of the transformer and alter the voltage regulation and efficiency.

Would a bad transformer cause the pump not to work?
Yes, a bad transformer can prevent a pump from working if the pump relies on electrical power supplied by the transformer. If the transformer is malfunctioning, it may not provide the necessary voltage or current to operate the pump, leading to failure. Additionally, if the transformer is damaged, it could cause electrical issues that may further affect the pump's operation.
What are to factors that affect the rate of weathering?
distance from the sea, ocean current
What does the emf equation of asingle phase transformer do?
The emf equation of signal phase transform
What are the five factors that affect current flow?
The five factors that affect current flow are voltage (potential difference), resistance (opposition to flow), conductive material, temperature (affecting resistance), and circuit configuration (series or parallel).
What factors affect your current financial position?
Overhead expenses, the economy, and poor credit.
What factors affect the inductive reactance of a coil in a A C circuit?
Current Flow I believe.
What happens to current in a step-up transformer?
Actually current transfomer is step up voltage transformer n step down current transformer as current transfomer is having single primary turn of thick conductor but having more number of secondary turn of thin wires..so wkt tansformer ratio k= n2/n1=v2/v1=i1/i2. so it steps up volatge n steps down current...so we use current transformer as a step up transformer almost in all generating stations. Current transformers typically have terminals for a voltmeter on their case and a hole through that case. If you run your current carrying lead through the hole and connect an appropriate voltmeter (the voltmeter's design and resistance may affect the results) to the voltage terminals, the voltmeter will indicate the current in the lead times some factor which should be marked on the current transformer. If you thread the current lead through the hole N times then the voltmeter will indicate N times what it would read with the lead going through once (assuming that the ampere turns resulting do not cause saturation of the transformer's core.
What factors affect the resistance and voltage?
Factors that affect resistance include material type, length, cross-sectional area, and temperature. Factors that affect voltage include the number of cells in a circuit, the presence of a power source, and the type of material conducting the current.
How are the factors affect the strength of the electromagnetism?
The core material and the number of windings are major factors. The voltage potential and current run the unit.
