What is mean by 2is to 3 turns ratio Transformer what is primary turns and secondary turns?
with an ideal electrical transformer with an input current of 2 amps and an output current of 1 amp what is the turns ratio of the secondary and primary coils
Is a phone a scientific invention?
Yes, it turns sound into electricity and back into sound on the receiving end.
What is the differences between current and potential transformer?
Current Transformer- Instrument transformer used for measure high current. it hasless and thin turns in primary and more and thick turns in secondary.Potential transformer- Instrument transformer used for measure high voltage. it has more and thin turns in primary and less and thick turns in secondary.CommentUnfortunately, the original answer has got things the wrong way around for the CT! A current transformer's primary has a thicker conductor than its secondary.
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.
When can be current in a primary coil induce a current in a secondary coil?
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.
Who invented the telephone and what was the technology used?
Alexander Graham Bell. He coupled the idea of a microphone to create a fluctuating electrical current in a wire to represent the sound, with the speaker which turns the fluctuating current back into sound.
How do you calculate turns ratio for current transformer?
The turns ratio is the number of primary turns divided by the number of secondary turns. This is the same ratio as input current to output current. ie the turns ratio N = I1/I2
How do you calculate primary current?
If it's a step up or step down transformer and you know the secondary side current, multiply the secondary current by the turns ratio. If you know the power in the secondary winding but not the current, divide the secondary power by the secondary voltage to get the secondary current and then multiply the secondary current by the turns ratio to get the primary current. The turns ratio is the number of turns on the secondary winding divided by the number of turns on the primary winding. For a step up transformer, the turns ratio will be greater then one. If it's a step down transformer, then the turns ratio will be less than one. If you don't know the turns ratio, divide the secondary voltage by the primary voltage to get the turns ratio.
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 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)
What is mean by 2is to 3 turns ratio Transformer what is primary turns and secondary turns?
with an ideal electrical transformer with an input current of 2 amps and an output current of 1 amp what is the turns ratio of the secondary and primary coils
What reference to a transformer the current times the number of turns is called the?
Transformer turns ratio
Is there sound that travels in currents?
No, sound is a wave not a current.
What turns sound energy into electrical energy?
A microphone
Is a phone a scientific invention?
Yes, it turns sound into electricity and back into sound on the receiving end.
What low pressure air current turns?
Clockwise
Explain the meining of modem?
Modem stands for MOdulate DEModulate it takes digital information from your computer and turns it into sound (the MOdulate portion) and turns sound into data (the DEMod part)
