Why wont a transformer function when supplied with direct current?

Transformers work on a principle called 'mutual induction' in which a changing current in one coil sets up a changing magnetic flux which links with a second coil, inducing a changing voltage into that second coil. I've emphasized the words 'changing' because its essential if mutual induction is to take place. Alternating current is a type of current that is constantly changing in value and direction, whereas direct current is a constant current -so transformers require a.c. to operate.

What type of transformer connection can be used when it is necessary to rectify alternating current into direct current with a minimum of ripple?
bride transformer
Will a bell ringing transformer operate on direct current?
No. Transformers always operate only on alternating current. They will burn up on direct current. That is, if the fuse does not blow first.
Why must you use ac current for transformer?
Transformer is based on the principal of mutual inductance.Induction is produced due to sinusoidal wave form thats why we use Alternating current inspite of Direct current.
What does ac stand for the mains voltage supplied in the UK?
AC stands for Alternating Current and DC stands for Direct Current.
Why cant you use a transformer to increase the voltage of a 60V solar panel?
The output of a solar panel is direct current. Transformers need alternating current to operate.

Why is it impossible to use a transformer on a direct current where the current is steady at all times?
alternating current has two halfs in one cycle.In one half it flows in one direction and in other half it flows in opposite direction.due to fluctuations ,alternating current has ability to produce phenomenon of mutual induction. and mutual induction is the basic principle on which a transformer works while direct current cannot produce phenomenon of mutual induction.thats why a transformer is not used on a direct current

Transformer is based on the principal of mutual inductance.Induction is produced due to sinusoidal wave form thats why we use Alternating current inspite of Direct current.
If the primary winding of a double wound transformer is supplied with the direct current its iron core will become magnetized but there will be no emf induced in the secondary winding?
BECAUSE YOU NEED AC EFFECT TO INDUCE EMF IN TO SECONDARY WINDING.OR DC PULSING.
What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A transformer is a device that changes the level of an a.c. voltage, while a rectifier is a device that converts alternating current to direct current.
What does ac stand for the mains voltage supplied in the UK?
AC stands for Alternating Current and DC stands for Direct Current.
What is the difference between a transformer and a rectifer?
A transformer is used to change the value of a voltage applied to the transformer's primary winding to a different voltage value taken from the transformers secondary winding. A rectifier is used to change an alternating current value to a direct current value.
What is the function of inverter?
It changes direct current (DC) to alternative (AC) energy.
4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
Why cant you use a transformer to increase the voltage of a 60V solar panel?
The output of a solar panel is direct current. Transformers need alternating current to operate.
Why are most chargers very inefficient?
Voltage must be changed by a transformer, and the alternating current changed to direct current by diodes. Each step has a loss of energy.
