A negative electron which is the moving from atom to the next

Question 6

What if we need in order to move charge

Answer 6

Charge carriers

Question 7

What is Current

Answer 7

When a charge flows from negative to negative

Question 8

What is conventional current

Answer 8

When charges flow from positive to positive

Question 9

Explain how electricity is created

Answer 9

Electrons in atoms can act as our charge carriers because they carry a negative charge. To create electricity you need to free an electron from an atom to force it to move. Using enough electrostatic force on the valence electron (either by pushing It with another negative charge or by attracting it with a positive charge) we can eject the electron from orbit around the atom creating a free electron. The free electron is pulled and prodded until it finds a new electron to latch onto In so doing the negative charge of the electron ejects another glance electron from the atom. This continues on and on
