Electrons are negatively charged particles. When a voltage difference exists, electrons are repelled from the more negative (or less positive) voltage toward the more positive voltage. If they are in a material which allows conduction of electricity, then the electrons will flow toward the more positive voltage.
You need a source of electrical potential difference, also known as voltage (which is the technical term for what for you call "electric pressure"). The easiest and most common voltage source is a household battery. Hook up the positive electrode of the battery using a conductor (eg. a copper wire) to one end of your circuit and the negative electrode to the other end, and voila, you'll have electric current flowing through your circuit.
Wires do not provide a voltage differenceAnswerAs 'voltage' is synonymous with 'potential difference', you appear to be asking "What does not provide a potential difference difference in a circuit?", which does not make any sense!
It may not be correct to say that an electric current will "flow into" circuits. Electrons move in a circuit in response to an applied voltage. And these electrons are alread in the circuit and available to support current flow if a voltage is applied. It may be more correct to say that electrons leave the negative terminal of a voltage source, and electrons enter the positive terminal of that voltage source. The electrons in the circuit that are availble to support current flow will "shift over" to create the current flow. Remember that the phenomenon of current flow in a wire is the "shifting over" of electrons in the wire. It's not about electrons going into one end of a wire and those same electrons coming out the other end. Use the link to the related question for more information that might help make things clearer.
An electric current through a resistive circuit can be increased by decreasing the resistive load or increasing the voltage of the circuit.
The force that makes electrons move is a voltage, or potential difference and both are measured in Volts. When electrons move, the rate of movement is current, measured in Amps. The amount of current is dependant on both the resistance in a circuit and the voltage. The higher the resistance, the lower the current. The higher the voltage, the greater the current. The symbol for voltage is "V" and confusingly, the symbol for current is "I". The unit of resistance is the Ohm with the symbol "R" or the Greek symbol for omega.
In an electric circuit, electrons are pushed by a voltage difference, also known as an electric potential difference. This voltage creates an electric field that exerts a force on the electrons, causing them to move through the circuit. The source of the voltage, such as a battery or power supply, creates this driving force for electron flow.
An electric potential difference, also known as voltage, creates an electric force field that moves electrons through a circuit. Electrons flow from areas of high potential (voltage) to areas of low potential, creating an electric current in the circuit.
The source of electrons in a circuit is supplied by an electric potential difference across two points . This potential difference in a circuit is called as voltage and is measured in joules per coulomb or volts.
The force that causes electrons to move in an electrical circuit is called voltage. Voltage is the difference in electric potential between two points in a circuit, which creates an electric field that pushes the electrons to flow from the higher potential to the lower potential.
The force that causes electrons to move in an electrical circuit is an electric field. When a voltage difference is applied across a conductor, the electric field exerts a force on the electrons, causing them to flow through the circuit.
Electrons are negatively charged particles. When a voltage difference exists, electrons are repelled from the more negative (or less positive) voltage toward the more positive voltage. If they are in a material which allows conduction of electricity, then the electrons will flow toward the more positive voltage.

Volta got an electric current when he connected the cells in a circuit because the cells produced a potential difference, or voltage, which created an electric field that allowed a flow of electrons to move through the circuit. This flow of electrons is what we call an electric current.
An electrical potential difference (aka. a difference in applied voltage), and a conductor / circuit. Electrons would help too.
An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).
Electrons flow in a circuit due to the electric potential difference, or voltage, between two points. This voltage creates an electric field that exerts a force on the electrons, causing them to move from a higher potential (positive terminal) to a lower potential (negative terminal).
Voltage in an electrical circuit is created by the difference in electric potential between two points, which causes the flow of electrons from a higher potential to a lower potential, generating an electrical current.
