Circuit: a closed loop of conductive material from one end of power source (-) to the other (+)

Series Circuit: circuit with single path and multiple components

Parallel Circuit: circuit with branches and separate paths for flow of charge

Charge: magnitude of electrical quantity

Power (p): rate of transferring electrical energy through a circuit (p = iv). Units - watts (W)

Coulomb's Law: the force of attraction/repulsion between 2 static charges is proportional to their charges and inversely proportional to the distance between them squared (F = kq1q2/r^2)

Resistance (r): amount the current is slowed/resisted through an obstacle. Units - Ohms (Ω)

Voltage (v): potential energy difference from one side of component to the other (drop/height). Units - Volts (v)

Current (i): flow of charge/electricity through circuit. Units - Amps (A)

Ohm's Law: voltage is equal to current times resistance (v = ir)

Flex Sensor: a sensor that measures the amount of bending and resistance
