If I am not wrong then you have asked about a transformer. And its a current transformer. By theory of voltage transformer we know that
Vs/Vp = Ns/Np
So for answering your question we need the value of number of turns in primary and secondary coil. But you can use this equation to find your answer if you have other values. By using ohmic law you can convert voltage to current.
The secondary current depends upon the load, not the primary current. Once you know the secondary current, you can then work out the primary current.
If a step-up transformer has 200 turns on the primary coil and 3000 turns on the secondary coil, with a primary coil voltage of 90 volts and current of 30 amps, then the turns ratio is 200:3000, so the secondary voltage is 1350 voltage and the available current is 2 amps. (This ignores losses through the transformer.)
The current flowing in the primary generates a magnetic field which induces a current in the secondary winding.AnswerNo current is induced into the secondary winding of a transformer. What is induced is voltage. Current will only flow in the secondary winding if it is connected to the load, and it is the load that determines the current, not the primary current.
The primary coil has to induce current in the secondary coil. The only way this can happen is if there is a varying magantic field in the primary which then will induce a varying mag field in the secondary which results in a current in the sec. Only varying current can induce a varying mag field only a varying mag field can induce current So you need a varying current in the primary. D.C. is not a varying current so it cannot induce a mag field in the coil. A.C. (it does not have to be +/- it just has to be varying) can do so.
A step-up transformer has 100 turns on the primary coil and 500 turns on the secondary coil. If there is 120 volts and 10 amps on the primary, what will be the current in the secondary? 2 amps.600v 2A
Because inductance is only related to alternating current. Direct current doesn't induce eletrical current on a secondary coil placed on a primary coil, because there is no frequency generated by direct current, and all you get is a single electrical current flowing through the wire without interfering with a coil placed near to the primary coil. What makes all the difference is the cycles per second that only alternating current can generate.
If the primary coil has ten loops and the secondary coil has five loops then the secondary coil works as a 50% step down
Secondary current = Primary current *(Number of secondary turns /Number of primary) turnsAnswerA current isn't 'induced' into the secondary winding of a transformer. It's a voltage that is induced into the secondary winding.Provided the secondary winding is connected to a load, the secondary voltage then supplies a secondary current which is determined from (Is = Vs/Rload). The primary current then depends upon the value of the secondary current and the turns ratio.
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.
It is reverse. when load current in the secondary changes the primary current also changes directly. Load current is dependent on the load. I am assuming that the question is related to a normal distribution transformer.
If a step-up transformer has 200 turns on the primary coil and 3000 turns on the secondary coil, with a primary coil voltage of 90 volts and current of 30 amps, then the turns ratio is 200:3000, so the secondary voltage is 1350 voltage and the available current is 2 amps. (This ignores losses through the transformer.)
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?"
The current flowing in the primary generates a magnetic field which induces a current in the secondary winding.AnswerNo current is induced into the secondary winding of a transformer. What is induced is voltage. Current will only flow in the secondary winding if it is connected to the load, and it is the load that determines the current, not the primary current.
1500A. You probably have pri / secondary confused. primary is usually used to denote the higher voltage winding, which will have more turns than the secondary. The secondary will have lower voltage, less turns, but will carry more current.
I assume that you are speaking theoretically, as it is unlikely that a practical transformer will have just ten turns ('loops') in its secondary coil. In any event, you have not provided sufficient information to be able to answer your question, as it's necessary to know how many turns there are on the primary winding.
when the current flow through primary coil an electromotive force generated to secondary coil in the direction that prevent the magnetic flux in the primary coil is called mutual induction.
150 amperesAnswerYour transformer's primary current will be:Is = Ip (Ns/Np) = 5 (90 000/300) = 5 x 300 = 1500 A
