In a DC circuit (battery), the lower potential is always on one 'end' of the circuit so the current always flows in the same direction.
In a AC circuit, a wave is generated so each end cycles between high and low potential. Current always flows towards lower potential and changes direction every time the higher/ lower potential changes
The current flowing in an electrical circuit.
A electrical from a battery is the flow of elecrons through a circuit in the opposite dirrection to the current flow. This current flow also happens inside the battery between the plates.
In an automotive electrical circuit, current is considered to flow from negative to positive in that circuit. Electrons leave the negative terminal of the battery, flow through any complete circuits, and return to the positive terminal of the battery.
Basically, one option - for providing energy to a circuit - is a cell or battery; the other option is to connect the circuit to an electrical outlet. With a cell, the current will be DC; with an electrical outlet, it will be AC (alternating current, that is, the direction of the current changes several times per second). You should also keep in mind the voltage - household current has a fairly high voltage (110 or 220 volts), compared to a cell (typically around 1.5 volts) or even a car battery (usually 12 volts).
Alternating Current and Direct Current. Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.

A diode.
Electrical current flow through a circuit is normally from negative toward positive.
The primary difference between DC and AC is the direction of current flow. In a DC circuit, all electron current flow is in one direction. In an AC circuit, current flows in one direction for part of the time, and in another direction for another part of the time. In the AC circuit, we'll see current flowing "back and forth" instead of the unidirectional current flow we find in a DC circuit.DC is "Direct Current", and AC is "Alternating Current". In DC, the current flow is in one direction only. In AC, the current flow is constantly changing direction.An example of DC is the output of a battery. An example of AC is the power present in a home electrical system.The current whose magnitude and direction remains change called as alternating current.The current whose magnitude and direction remain unchanged called as d.c. Current.
The electrical pressure is created inside a battery and it provide the voltage which creates orr pushes current to flow in the circuit.
The battery is the power source of the circuit. It supplies current to the circuit and the circuit is simply a path for the current to follow. When you remove the current (battery), the path still exists but there is no current going through it.
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.
