Would you expect to find an alternating or direct current in the secondary coil of a transformer?

An Alternating Voltage is induced in the secondary winding. When connected to an external load, you will have an alternating current.

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.
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.
Lightning carries Alternating current or Direct Current?
Power lines carry electricity as alternating current.
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
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.
Why a transformer only work with alternating currents?
The iron core of a transformer holds a magnetic field when energized by the primary windings that conduct current. It is the building up and collapse of the magnetic field that induces current in the secondary windings. Direct current has no build up or decay of magnetic field (except when turned on and shut off) so no current is induced in the secondary windings.
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 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
Why the solar panel power cannot be transfer to the meter?
Solar panels are direct current (DC), the electric in the meter is alternating current (AC). You need a special transformer to convert from direct to alternating. This usually has to be done since everything in your house usually runs on alternating current.
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.
How do you test chopper transformer?
A chopper transformer is a kind of transformer used in an switching power supply.The primary input voltage of it is a Direct current (D.C) unlike any other ordinary step down transformer which uses an Alternating Current (A.C).Chopper transformer uses a switching transistor to produce a secondary voltage..
Is your house alternating or direct current?
Alternating current. Direct current is used in batteries.
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.
How does ac dc power supplies work?
The mains to the house is an alternating current and this high voltage is stepped down using a transformer. The low voltage secondary alternating current is converted to direct current using 4 diodes wired as a bridge rectifier. The 'lumpy' direct current is smoothed using an electrolytic capacitor to smooth the resulting dc. It may need to be voltage regulated if the circuits it feeds are voltage sensitive.
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.
