To be precise, a current doesn't flow - a current "is". Although many people - including myself - often use the informal term "a current flows". The particles that make up the current do flow - or move.
An electrical current involves the movement of some type of charged particles. Often, these are negative electrons, but there are other possibilities, as well, especially positive holes, and negative or positive ions.
A: the answer lies with the power consumption of any device while operating normaly.
There are two ways to look at current. Conventional current (measured in amps) flows from positive to negative. This model works for the vast majority of electrical engineering purposes. However, current is created by the movement of electrons. Electrons have a negative charge so electrons moving in one direction will give rise to conventional current in the opposite direction. Therefore, although current flows from positive to negative, electrons flow from negative to positive.
The voltage applied and the resistance across it.
A path that is made for an electric current is called a circuit. The two main components in a circuit are the load and a source which are combined with conductors and as a whole form a circuit.
No current flows when the the voltage is zero.
The electrical current for a home device travels in a circuit.
DC.
An electrical current.
When an electrical current flows through a wire, it creates a magnetic field around the wire.
Yes, the current in an electrical circuit can be negative if it flows in the opposite direction of conventional current flow.
False. Electrical current flows from a high pressure state (called hot) to a state of rest (called ground or neutral).

When an electrical current flows through a wire it creates what is called an Electro Magnetic Field.A magnetic field is create when an electric current flows through a wire.
The unit to describe the amount of electrical current passing through a point is the ampere (A).
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
The black wire is the hot wire through which the electrical current flows to the appliance. The left over voltage which is usually zero flows back to the main circuit panel through the white neutral wire where it flows to ground.
