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.
An electrical circuit is an example of an electrical pressure to electrical current convertor.
The electrical current for a home device travels in a circuit.
DC.
An electrical current.
False. Electrical current flows from a high pressure state (called hot) to a state of rest (called ground or neutral).
parallel circuit
negative to positive during use
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.
power surge
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
C
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.
When electrical current flows through a lightbulb (whether it's CCFL, halogen, or incandescent), the trade-off is light and heat energy.
