I assume you are talking about currents in the ocean. Well the push and pull of the moon largely controls the tides of the ocean. However, in certain areas of the world monsoons play an evern larger part regarding the patterns of the currents.

It is the flow of negatively charged particles, i.e. electrons.
Current is inversely proportional to the resistance of the circuit. Resistance goes up, current goes down. Resistance goes down, current goes up.
The effect of an open circuit is that no current will flow.
The AC current tend to flow on the surface of the conductor. The higher the frequency, the thinner the skin. This is known as the skin effect. So DC current flow throught the entire conductor but when the signal varies (AC) there is the formation of eddy current in the conductor itself and that pushes the electrons at the surface of the conductor. You can get more information on the skin effect and skin depth on wikipedia : http://en.wikipedia.org/wiki/Skin_effect http://en.wikipedia.org/wiki/Skin_depth
Electron flow is from negative to positive. Conventional current flow is from positive to negative.

It increases resistance.
Thet resistor opposes the flow of current through it becoz of its internal construction. Its material has opposing property.
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
The number of batteries has only an effect on the amount of current when they are equivalent and connected in parallel. The amount of current that can flow from a group of batteries connected in series is limited to the current provided by the battery that produces the lowest current flow in the string.
a current flow close to a magnetic source it influence the sources hall effect is a disturbed signal as a function of speed.
You apply a voltage across a load and the result is that a current flows through the load. So you must have the voltage present, the cause, before current flow, the effect. Think of voltage as pressure and current as flow.
Conventional current flow refers to a flow of positive charges. It is a kind of ficticious current. If - as is often the case - the real current is an electron flow (negative charges), then the conventional flow is a current in the opposite direction as the electron movements, since this would have the same effect (for example on the magnetic field, or on conservation of charge).
It is not true that the Doppler effect has anything to do with electricity and the flow of current. The Doppler effect involves pitch and sound frequency of moving objects, for example the apparent noise changes of an approaching car.
flow of electrons is not visible.only it can be sensedAnswerCurrent can only be detected through one or more of its effects. There are three effects of an electric current: heating effect, magnetic effect, and chemical effect. We use the magnetic effect (the force between currents in parallel conductors due to their magnetic effects) to define the ampere.
Loads do not 'slow down' electron flow. They effect the magnitude of a current, not its speed!
It is the flow of negatively charged particles, i.e. electrons.
