- Voltage is the energy per charge that moves electrons from one point to another.
- DC current from a battery always flows in the same direction.
- AC current alternates direction with voltage.
- In a series circuit, the current through each component is the same.
- In a parallel circuit, the current splits between different branches.
- Parallel circuits have advantages over series circuits, such as each device having its own pathway for current.
- Power is the rate at which energy moves through a circuit.
- The watt is a unit of power.
- Ohm's law states that current is equal to voltage divided by resistance.
- The formula for electric power is P = V x I.
