Describe the structure of the atom as it pertains to electrical energy.
Electricity flows as an electrical current, the flow is made of electrons and are subatomic particles.
Explain the difference between electron flow and conventional
1. Describe the difference between DC and AC current and voltage.
DC current is direct, it always flows from negative to positive. AC current on the other hand,
alternates. So at a given time, current can be flowing in either direction.
