Study Notes

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.
