in an adjacent coils ,the current flows in same direction so there is force of attraction shortening the coils.

Is your house alternating or direct current?
Alternating current. Direct current is used in batteries.
What is the simplest source of direct current?
Simple source of direct current are Batteries.
What is a constant current?
DC or Direct Current. The current is no alternating.
What is the purpose of the inverter In a photovoltaic solar power plant?
Ernie Ramhoff
High frequency is direct or indirect current?
-- There's no such thing as 'indirect' current.-- Direct current has no frequency. As soon as you mention 'frequency',you're talking about alternating current.
What happens if a direct current is put through a coil suspended between the poles of a magnet?
The coil will align itself with the magnetic field (poles) of the magnet.
Is it true the alternating current can pass through a capacitor while the direct current cannot pass through?
Yes.
What is the continuous loop that an electric current flows through?
DC = direct current.
What is a direct currnet?
Direct current is a flow of electricity which only goes one way. Batteries, for example, produce direct current, so the current must flow all the way through a circuit and back into the battery to work. Alternating current is what comes out of a wall outlet, and it alternates in both directions, with current flowing in and out of the outlet.
Will a battery supply direct current or alternating current or ac?
direct current.
How electricity travels through power cords?
It's called Alternating Current (AC) as opposed to Direct Current (DC/batteries).
Seguence of operation for a direct ignition gas furnace?
If the furnace is direct ignition, The HSI or spark ignites the flame. A flame sensor passes current through the flame, if current is present the main.
What happens when electrons move from one object to another through direct contact?
friction that the answer
How many types of direct current and what is the frequency of direct current?
There is only one type of direct current and its 'frequency' is zero.
What is the difference between Direct Current positive and Direct current negative?
Direct Current Positive - the starting point at which the electrons flow through the wire circuit. These electrons are fully charged, ready to expend their energy into the various points in the circuit, be it a lightbulb etc Direct Current Negative - the return point of the finished electrons into the battery to collect more energy to enter the circuit again.
What is DC power?
Direct current (DC or "continuous current") is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also be through semiconductors, insulators, or even through a vacuum as in electron or ion beams. In direct current, the electric charges flow in the same direction, distinguishing it from alternating current (AC). A term formerly used for direct current was Galvanic current. Direct current may be obtained from an alternating current supply by use of a current-switching arrangement called a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be made into alternating current with an inverter or a motor-generator set. The first commercial electric power transmission (developed by Thomas Edison in the late nineteenth century) used direct current. Because of the advantage of alternating current over direct current in transforming and transmission, electric power distribution today is nearly all alternating current. For applications requiring direct current, such as third rail power systems, alternating current is distributed to a substation, which utilizes a rectifier to convert the power to direct current. See War of Currents. Direct current is used to charge batteries, and in nearly all electronic systems as the power supply. Very large quantities of direct-current power are used in production of aluminum and other electrochemical processes. Direct current is used for some railway propulsion, especially in urban areas. High voltage direct current is used to transmit large amounts of power from remote generation sites or to interconnect alternating current power grids.
Which would make more shock the alternating current or direct current?
direct current
