According to Faraday's Law only if there is change in flux linkage of a conductor then current is induced between mutual inductors.
Now DC will induce a constant a constant flux in the transformer core, consequently in the secondary coil. So constant flux cannot induce a current in the secondary.

What do transformer coil have to do with the way the transformer control voltage in alternating current?
Transformer coils are normally used to step down power from high power lines to a power you can actually use in your house. This works through the ratio of windings on a coil to the windings on the output side.
What is the difference between transformers and adapters?
A transformer is a component that changes AC current from one voltage to another. A transformer consists of two coils, one connected to the input, and one connected to the output. A transformer can convert voltage up or down, depending on the number of windings on the coil. An adapter MAY include a transformer to change the voltage, but an adapter usually changes the voltage AND converts from AC to DC as well, and may have a regulator that locks the voltage to prevent a surge and other components that prevent what is called "ripple".
What is uses of tapped coil?
If question is about a transformer's tapped coil then the taps are a way of getting different voltages from one transformer. The end of the transformer's coil is the common point and the taps to this common point will give different voltages depending on where in the coil the taps are taken from.
A transformer is a device used to increase or decrease dc voltage?
The answer below this is not correct, a transformer can only be used on AC not DC. So the statement, "A transformer is a device used to increase or decrease DC voltage" is false The above comment relates to an entry which was obviously deleted. However, the above comment is also false. The ignition coil in of a petrol engine is a transformer, a pulse transformer. It's d.c. which passes through the primary, not a.c. <<>> A: this is a passive component as opposed to a device that is active answer is yes it does that but more importantly it isolates and match in/out impedance's
What kind of device is a telsa coil?
Tesla coil is a resonant air core transformer. There are other known devices that are like the Tesla coil.
What is a transformer called that increases voltage?
A transformer that increases voltage is a step-up transformer.
Which type of current does a transformer work with?
A transformer works with alternating current (AC). The primary coil of the transformer is connected to an AC power source, which creates a changing magnetic field that induces a voltage in the secondary coil.
Can you use a step down transformer as a step up transformer by reversing the secondary voltage as a primary voltage?
Yes a Tesla coil or ignition coil is an example.
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.
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 a car coil?
The coil is a high voltage transformer, used to step up battery voltage to 50,000 volts to fire the spark plugs.
What Device used to select amount of voltage in primary coil of step up transformer?
There is no selective device to determine the amount of voltage. A transformer is selected by the voltage available at the site for the primary and the load on the secondary side of the transformer.
How does a Tesla coil work to generate high-voltage electrical currents?
A Tesla coil works by using a transformer to increase the voltage from a power source to create high-voltage electrical currents. This high voltage creates a strong electric field that ionizes the air around the coil, allowing electricity to flow through the air in the form of sparks or arcs.
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).
. 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).
If a transformer has 1000 turns of wire in the primary coil and 50 turns in the secondary coil if the input voltage is 2400 V what is the output voltage?
120 v
What happens when a light bulb is connected to the output coil of the transformer?
Assuming that the voltage rating of the lamp matches the rated secondary voltage of the transformer, the lamp will operate at its rated power.
