Electric charge occurs when atoms are stripped of their electrons by an external force. They become charged ions and can be seen most dramatically when friction of moving ice particles in clouds create huge voltages of static charge which finally discharges as a lightning bolt.

Charges move in a circuit due to the presence of an electric field created by a voltage source, such as a battery. The electric field exerts a force on the charged particles, causing them to flow through the circuit. This flow of charged particles constitutes an electric current.
The great gods of Mount Olympus managed to do this incredible feat a mere 1500 years ago, and passed its secrets down to mankind. In order to uncover this secret, you must watch Percy Jackson: The Lightning Thief. The movie accurately displays how a charge flows, and I think you'll find it most useful.
But if you wanna take the shortcut and get the answer fast, I suggest looking in your science textbook.
There is a difference between a charge and a static charge. A static charge occurs when positive and negative electrons separate themselves to form a conduct charge.
Charges leave the dry cell. Charges move through the switch. Charges move from the switch to the light. Charges move through the light bulb. Charges move through the wire leading back to the dry cell.
Current in an electric circuit is caused by the movement of electric charges, usually electrons, through a conductor. This movement is typically initiated by applying a voltage difference across the circuit, which creates an electric field that pushes the charges. The current flow will continue as long as there is a closed path for the charges to move through.
A voltage.
the electrons are not allowed to enter into the circuit.
The pushing power of an electrical source is referred to as voltage. Voltage is a measure of the electromotive force that causes electric charges to flow in a circuit. It is measured in volts (V) and determines how strongly the electrical source can push charges through a circuit.
