current: the flow of electricity (I/A/Amps(ampere)

voltage: the force pushing the electricity (V/V/Volts)

Resistor: something that restricts the flow of electricity (R/Ω/ohlms

circuit: a never ending loop

LED - lets current through 1 way and produces light

CELL - Source of electricity. More that 1 equals battery.

resistor - Restricts flow. Provides resistance.

capacitor - stores electric charge until discharged.

Transistor - acts like an electronic switch

toggle switch: opens and closes the circuit

Buzzer: makes noise

variable resistor: controls resistance

transistor (PNP)

thermistor: senses heat

LDR/photoresistor

resistance in series: R total = R1+R2+R3
