Current definitions

Series Circuit - A circuit that has one path. All loads are connected in one concurrent path that flows from one end of the battery to the other. The whole current flows through each component.

Parallel Circuit - an electrical circuit in which current flows in more than one path at the same time.
Potential Difference - The energy stored in an object - “the higher the hill the more potential energy it has”

Electric Current - A measure of the amount of electric charge passing by a point in each electrical current each second. DC - Direct current - current flowing in 1 direction , i.e batteries - AC (alternating current) flows back and forth in cycles , i.e homes

Electric potential (V) - Measured in volts, speed of moving electrons. High voltage = High speed, Low Voltage = Low speed

Amperes (A) -  The measure of a current in a circuit. It is the number of moving electrons - a high current has many electrons and a low current has few.

Ammeter - used to measure current, must be connected in series and e- must flow directly through it to get a measurement.

Voltmeter - used to measure potential difference across any 2 points in a circuit or the energy used by a load. Connected in parallel around a load (i.e a lightbulb)
Resistance - The degree a load slows electric current. They convert kinetic energy (energy due to motion) to other forms of energy, most notably heat.

Energy - The ability to do work. The energy transferred to an electrical load by moving charges. The symbol for electrical energy is E and it is measured in Joules (J)

Power - How quickly or slowly a load uses energy. If the load uses energy quickly it has high power and if it uses energy slowly it has low power. It is measured in watts. (W)
