A dynamo.
It is hard to produce pure direct current using the induction of a magnet on a coil.
In a rotating coil the north and south poles of a magnet will normally cause the current to flow the opposite way, every half turn.
In a dynamo, the spinning electromagnet in the centre of the field coils, has many separate windings. The current is switched to each coil make sure the magnetism only has one polarity, at each fraction of a turn. This switch is called a commutator.
Batteries produce DC because the potential difference is determined by the chemical reaction inside the battery. This voltage is constant.
A Direct Current or DC direct current is a current consisting of charges that flow only in one direction.
Direct Current. His opponent, Nikolas Testa, wanted Alternating Current.
There is two types of current. Direct current and alternant current. The one running in only one direction is Direct current.
a battery always produces a direct current.the electrons always travel from the negetiove to the positive terminal.But the direction of the current is the opposite that is from the positive to the negetive terminal.
An electrical device that converts alternating current to direct current is known as a rectifier. An inverter is a device that converts direct current to alternating current.
Some possible answers are: a battery (which produces direct current) or a generator of electricity generator, such as a dynamo (which produces direct current) or an alternator (which produces alternating current).
A dry cell battery does not use current it produces a current when connected to an electrical load. The type of current that the dry cell produces is DC (direct current).
An inverter
An a.c. generator produces alternating current, whereas a d.c. generator produces direct current.
A Rectifier converts Alternating current into Direct current
It's called an inverter.
A diode does that.
Invertor
A dry cell produces direct current, which means that the current flows from one terminal of the dry cell to the other in one direction only. The word generator nowadays often means a device that produces alternating current, which is to say current that reverses its direction, usually at a fixed rate called the frequency. For instance, the current available in North American homes is alternating current at 60 cycles per second; it reverses direction 120 times per second. A machine that produces current that resembles what is available from a dry cell is often called a dynamo. These devices are similar to generators but with switches in them to change the alternating current to direct current, in effect. The current they produce is still not quite like that from a dry cell inasmuch as it's not perfectly 'smooth' continuous direct current. There's a ripple of slightly higher and lower current superimposed on the direct current. Please see the link, especially the graph associated with the Gramme dynamo.
No. A battery produces DC, or Direct Current.
directA dry cell battery produces DC.
