What coil will be greater if the primary coil of a transformer has 40 turns and the secondary coil has 60 turns?
The secondary coil will have greater inductance compared to the primary coil because it has more turns. The inductance of a coil is directly proportional to the square of the number of turns, so increasing the number of turns increases the inductance.
How the input voltage is changed to an output voltage in a transformer?
Transformers work on the induction principal of the flux of the primary winding cutting the wires of the secondary winding. The amount of turns in the primary in relationship to the amount of turns in the secondary is the transformers winding ratio. This ratio is what governs the voltage value of the secondary winding.
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.
What is a transformer called that increases voltage?
A transformer that increases voltage is a step-up transformer.
How do you increase or decrease voltage?
This question makes no sense as written. However, maybe it will help to know that for a given load if you increase voltage the current increases proportionally and if you decrease the voltage the current decreases proportionally. Ohm's Law says Voltage = Current x Resistance.

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.
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.
. 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).
How the secondary voltage in transformer is stepped up?
The secondary voltage in a transformer is stepped up by having more turns in the secondary coil compared to the primary coil. This creates a higher electromagnetic induction which leads to a higher output voltage. The ratio of the number of turns in the primary coil to the number of turns in the secondary coil determines the degree of voltage stepping up.
What is the difference between a secondary and primary coil?
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).
What does a step up transformer do to increase the voltage of an electrical current?
A step-up transformer increases the voltage of an electrical current by having more turns in the secondary coil than in the primary coil. This causes the magnetic field to induce a higher voltage in the secondary coil, resulting in an increase in voltage.
What is the maximum voltage on the secondary side of the transformer?
Transformers come in very many varieties and voltages. Transformers have ratings regarding the electrical power that they are connected to. The most important ratings are voltage, power and current. In general the insulation level and number of windings in the secondary and primary determine the maximum rated voltage, and the size of the magnetic wire that makes up the windings, and mass of the iron core, determines the rated power and rated current. It is the insulation level therefore, that determines the maximum, safe voltage that can occur on both the secondary side and the primary side. The turns ratio between the primary and secondary coils of the transformer determines the secondary voltage with respect to the primary voltage. If the primary coil has 1000 turns, and the secondary coil has 100 turns, the transformer turns ratio (usually designated by the letter "a") is 100 / 1000 = 0.1. If a = 0.1, then if 1000 volts are applied across the primary coil, ideally, 100 volts will be measured across the secondary. Transformers have been manufactured with secondary voltage ratings in the range of millivolts, to 1,000,000 volts.
