components circuit Flashcards
cell?
transfers chemical energy into electrical energy
one long line followed by short
connecting wire
join components with straight lines
straight line
diode
allows electric current to flow in one direction only
circle with triangle with point on end
resistor
restricts the flow of charge in a circuit
rectangle
variable resistor
changes the resistance of a circuit to control the current
rectangle with diagonal arrow through
light dependant resistor
a component that decreases resistance as light intensity increases
rectangle in circle with two arrows pointing towards it
thermistor
a component that decreases resistance and temperature increases
rectangle with upside down hockey stick through
dude
a component that breaks the circuit if the current is to high
rectangle with line through
open switch
no charges flow, there is no current
line coming up on diagonal
lamp
transfers electrical energy into heat and light
circle with cross in
voltmeter
measured the potential difference (voltage) across components in volts (V)
circle with V in
ammeter
measures the current in amps (A)
circle with A in
closed switch
allows charge to pass, there is a current if the circuit is complete
straight line with two circles
battery?
two or more cells together
three long followed by short lines
