Primary and secondary are only terms of convenience based on the ratings and purpose of the transformer. If a transformer is labeled 120 to 240 volts, just pick a winding and apply 120 VAC. If the output is 240 volts you found the primary and secondary. If you apply 120 volts and get 60 volts out that means the side where you applied 120 VAC is the secondary.

What are the two coils in a transformer?
primary and secondary coilsAnswerPrimary and 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.
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.
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
What happen to the secondary circuit if the primary circuit is close?
If the primary circuit is closed, the current will flow through the primary coil, inducing a magnetic field. This magnetic field will in turn induce a current in the secondary coil, allowing for the transfer of energy from the primary to the secondary circuit.
Which device tranfers electrial energy from a primary coil to a secondary coil induction?
transformer
A transformer for a laptop computer converts a 120 volt input to 24 volt output show that the primary coil has fives times as many turns as the secondary coil has?
To convert voltage from primary coil to secondary coil in a transformer, you can use the formula VP/VS = NP/NS, where VP is primary voltage, VS is secondary voltage, NP is number of turns in primary coil, and NS is number of turns in secondary coil. Given VP = 120V, VS = 24V, and we need to show the primary coil has 5 times as many turns as the secondary coil. Plug in the values: 120/24 = NP/NS. Solving for the ratio of turns, we get NP/NS = 5. This means the primary coil has 5 times as many turns as the secondary coil in this transformer scenario.
. A step-up transformer has a primary coil with 100 turns and a secondary coil with 25 turns. If the input voltage in the primary coil is 40 volts what is the output voltage reduced to in the secondar?
The output voltage in the secondary coil would be increased. Using the transformer formula Vp/Vs = Np/Ns (where Vp = primary voltage, Vs = secondary voltage, Np = number of turns in primary coil, Ns = number of turns in secondary coil), we can calculate the output voltage to be 160 volts (40V * 100/25).
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.
Is it true that electrical energy is converted to magnetic field energy in the secondary coil and magnetic field energy converted to electrical energy at the primary coil?
yes it is the primary coil being somthing such as a tubine, and the secondary the generator
