The primary coil is the one with voltage applied, or the 'input'.
The secondary coil is the one in which a voltage is induced by electromagnetism, or the 'output'.
In a step up transformer, the secondary coil voltage is higher than the primary.
In a step down transformer, the secondary coil voltage is lower than the primary.
In an isolation transformer, the secondary coil voltage is the same as the primary. Here, the point of the transformer isn't to raise or lower voltage, but to keep a particular circuit electrically disconnected from another circuit, while still allowing the circuits to function together (through electromagnetism).

∙ 6y agoPut simply, the primary and secondary coils in a transformer are wound around a core of some kind to facilitate electromagnetic coupling between those coils. It's that coupling that allows voltage in the primary windings to induce voltage in the secondary windings.

What is the current in the secondary coil fi the current in the primary coil is 5.0A 10 loops on primary coil and 20 on secondary coil?
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.
A stepup transformer has 100 turns on the primary coil and 500 turns on the secondary coil If the primary voltage is 120 volts what will be the secondary voltage?
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
A step-up transformer has 300 turns on the primary coil and 90000 turns on the secondary coil if the current flowing through the secondary is 5 amps what is the current flowing in the primary?
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.)
Why is the number of turns in primary coil more than that of the secondary coil?
The number of turns or windings of a transformer can vary. There can be more in the primary, or more in the secondary, or there can be an equal number in a transformer that is simply used for isolation (an isoformer). More turns in the primary than secondary will create a step down transformer. More turns in the secondary are found in a step up transformer. The transformers on power poles have more turns in the primary to step the line voltage down for delivery to residential customers.
What are taps for in a transformer?
The ratio of windings between a primary and secondary in a transformer govern the output voltage. Multiple taps are connections to various points in the coil effectively changing the winding ratios to get multiple voltages from the same transformer. Taps can be on the primary, secondary or both to provide a more versatile transformer.
Difference of step up and step down in terms of no of loops in the secondary coil?
If the primary coil has ten loops and the secondary coil has five loops then the secondary coil works as a 50% step down
A step-down transformer has 525 turns in its secondary and 12500 turns in its primary If the potential difference across the primary is 3510 V what is the potential difference across the secondary?
The potential difference across the secondary coil will be 147.42 Volts
What is difference betweena step up transformer and step down transformer?
The difference between the two transformers is the coil ratios between the primary and secondary windings. A transformer that increases voltage from primary to secondary has more secondary winding turns than primary winding turns and is called a step-up transformer. Conversely, a transformer with fewer secondary windings does just the opposite and is called a step-down transformer.
What are the two coils in a transformer?
primary and secondary coilsAnswerPrimary and secondary windings.
How does a power mat for an Android device work?
The primary coil is in the power mat while the secondary coil is in the Android device. Power goes from the primary coil to the secondary coil, which allows the phone to charge.
If the voltage in a transformer is twelve volts and the primary coil has ten turns and the secondary coil has twenty what is the voltage across the secondary coil?
I assume the primary has 12 volts applied. The voltage ratio from primary / secondary is equivalent to the turns ratio = 10/20, so the primary voltage is 1/2 of the secondary voltage. The secondary voltage is 24.
What is meant by a primary coil and a secondary coil?
In a transformer, the primary coil is the coil that has voltage applied to it. The secondary coil is the coil that we take voltage from. Transformers are used to step up voltage, step down voltage, or simply to isolate circuits.
How do you repair a 1992 Suzuki GS500 motorcycle coil?
You cannot repair a motorcycle coil. Best bet is to test the coil to ensure it is bad. Your Suzuki should test between 3-6 ohms on the primary and secondary coil connections and between 18,000-30,000 when testing between the secondary and the plug wire.
Which device transfers electrical energy from a primary coil to a secondary coil induction?

Which device tranfers electrial energy from a primary coil to a secondary coil induction?

Does the ratio of voltage in a primary coil to secondary coil depends on the turn of each coil?
Yes, although the question is poorly formed. The ratio of the voltage in the primary winding to the voltage in the secondary winding is the same as the ratio of the number of turns in the primary winding to the number of turns in the secondary winding. For example, if the primary had 1200 turns with the secondary having 120 turns, and the primary voltage was 50 volts, then the secondary would be 5 volts. This is a ratio of 10:1.
