How many amps does a 277 volt primary and 120 volt secondary transformer draw with 6 amps on the secondary?
Assuming the transformer is ideal, the current on the primary side can be calculated using the formula for power: P(primary) = P(secondary). Since power is the product of voltage and current, the current on the primary side would be 1.38 amps (277V x Iprimary = 120V x 6A).
What type of succession is the current ecosystem in?
It depends on just where the ecosystem is located.
What is the current rating of the fused switch assimblies in the primary distribuiton center?
The fused switch assemblies in the primary distribution center have a current rating of [provide the specific rating found in the system or documentation]. It is important to refer to the equipment's specifications for accurate information.
What is Low current electrical systems?
This refers to the electric current in amps. There is no definition of what constitutes a low current, but in electronics it might refer to less than 1 mA, while in domestic power supply it might mean less than 5 amps.
Denotation is the specific definition of a word according to the dictionary?
Yes, denotation refers to the literal or primary meaning of a word found in the dictionary. It is the explicit definition of a term, stripped of any connotations or additional meanings that the word may have in different contexts.
What is the definition of transformation ratio?
The turns ratio of a transformer is the number of primary turns to secondary turns. This defines how the transformer will change the voltage and current. For N1 primary turns, and N2 secondary turns, N1/N2 will be the turns ratio; the secondary voltage will be:the primary voltage x (N2/N1); The secondary current will be:primary current x (N1/N2)
How does the product of voltage and current in the primary compare with the product of voltage and current in the secondary?
The current in the secondary when the voltage is twice the primary will be one half of the primary. The current in the primary when the voltage is twice the secondary will be twice the secondary.
What is full load-current in primary?
This is the current flowing in the primary circuit when full-load current flows in the secondary circuit.
How calculate primary current in transformer the 50kva rating and 11kvprimary voltage?
The primary current is determined by the secondary current. So, if you don't know the secondary current, you cannot work out the primary current.If the secondary isn't connected to the load, then the primary current is simply the primary voltage divided by the impedance of the primary winding.You can, though, work out the 'rated' primary current (i.e. the value of current the primary can carry, continuously). For a single-phase transformer, this will be its rated apparent power (in volt amperes) divided by its rated primary voltage. So, in this particular case, we are looking at:rated primary current = (50 x 103) / (11 x 103) = 4.55 A
When secondary coil is open there is no current in the primary coil WHY?
I am assuming the question is about the power / distribution transformer and not the current transformer. The primary current is a function of load connected on secondary. With the open secondary, there is no load, no current, it is open circuit. Hence no primary current. However there is always some small amount of no load current in the primary winding.
What is the current in the secondary coil if current in primary is 5.0A?
It depends on the turns ratio between the primary and the secondary. If the ratio were 10:1, a step-down transformer, for instance, the current in the secondary would be about 50A. If it were 1:10, a step-up transformer, however, the current in the secondary would be about 0.5A.AnswerThe primary current doesn't determine the secondary current. The secondary current is entirely-dependent on the secondary voltage and the impedance of the load. It is this secondary current that the determines the primary current. So you should be asking, "What value of secondary current would result in a primary current of 5.0 A?"

Formula for relation between primary winding and secondary winding?
The turns ratio of Primary / Secondary tells you have the voltage and current will be changed. The secondary current will be (primary turns/secondary turns) times the primary current, and the secondary voltage will be (secondary turns / primary turns) times the primary voltage.CommentThe above answer is a little misleading, because the secondary current is determined by the load, and not by the transformer's ratio. It would, therefore, be more accurate to say that the primary current would be equal to the secondary current times the (primary turns/secondary turns) -i.e. not the other way around!
What is Primary Current?
Primary current is a flow to be measured that cannot be safely passed through the measuring device. A current transformer is used to provide a lower level, secondary current that can be passed safely through the measuring device. Primary current is measured as a secondary current, multiplied by the turns ratio in the current transformer.
Does a transformer increase amps?
The primary current is determined by the secondary current, not the other way around. For example, a step up transformer will step up the primary voltage in proportion to the turns ratio of the transformer. Any secondary current is then determined by the secondary voltage and the load, NOT by the primary current. The primary current is then determined by the secondary current in proportion to the reciprocal of the turns ratio.
What is the definition of electric current the the units of electric current?
ampere
