The main thing to know about electricity is that if you don't have a closed circuit, nothing will happen!
Current flows form the positive to negative terminal of the battery. Current can be "carried" by electrons flowing from positive to negative.
You can have voltage without current but not current without voltage.
This is because:
"Voltage is the cause, current is the effect" (Hewes, John. 2011)
Voltage is the the energy that the current is carrying around the circuit.
If he circuit is closed and complete, then the voltage can "push" the current around the circuit.
However, if there is a break in the circuit and it is not closed or complete, then the voltage can still be present but there will be no current
because there is nowhere for it to go and it cannot complete the charge ( Hewes, John. 2011).

Voltage is the highest when it is closest to the positive side of the battery and gets lower as it moves toward the
negative side of the battery. This is because voltage decreases as it gets further away from the
positive side of the battery because of the resistance.
