Circuit Diagrams Flashcards
(9 cards)
open switch
A switch that is not conducting electricity
An open switch prevents current from flowing through a circuit.
What is a Lamp?
An electrical device that produces light
Lamps can be incandescent, fluorescent, or LED.
What is an Ammeter?
An instrument used to measure electric current
It is typically connected in series with the circuit.
What does LDR stand for?
Light Dependent Resistor
LDRs change resistance based on light intensity.
What is a Variable resistor?
A resistor whose resistance can be adjusted
Commonly known as a potentiometer.
What does LED stand for?
Light Emitting Diode
LEDs emit light when an electric current passes through them.
What is a Closed switch?
A switch that is conducting electricity
A closed switch allows current to flow through a circuit.
What is a resistor?
An electrical component that limits current flow
Resistors are used to control voltage and current in circuits.
What is a Thermistor?
A type of resistor whose resistance varies significantly with temperature
Thermistors are used for temperature sensing and control.
