circuit symbols
the full and halt line would represent
a battery
This component supplies energy to the circuit.
a battery or cell
In this type of circuit, all components are connected one after another.
what is a series circuit
In a diagram, what direction does current flow from the battery?
from positive to negative terminal
A student draws a battery backwards. What’s the mistake?
reversing the positive and negative ends
the circle with x would represent
lightbulb
This device measures the current flowing through the circuit.
an ammeter
In this type, components are on separate branches.
a parallel circuit
If a voltmeter is shown across a bulb, what is it measuring?
voltage
A student connects a voltmeter in series. What's wrong?
voltmeters must be in parallel
the up and down symbol stands for
fuse
This device opens or closes the circuit.
a switch
Which circuit keeps other bulbs lit if one goes out?
parallel cirtuit
Where should an ammeter be placed in a circuit?
in series with the component?
Why is using only one wire from the battery wrong?
circuits need a complete loop
the cirtle with a represent
ammeter
This component resists the flow of electricity.
a resistor
In which circuit does current split between branches?
parallel circuit
What happens to total resistance in a series circuit with more resistors?
it increases?
What mistake is made if all bulbs go out when one breaks?
using a series instead of parallel
the symbol with a v represents
voltmeter
converts electrical energy to light
a light bulb
Which type of circuit is used in most homes?
parallel cirtuit
What does it mean if no current flows in the diagram?
the circuit is open or broken
What does it mean if a circuit is drawn with no power source?
there will be no current
