Circuits Flashcards
Every point in a circuit has a…
voltage
All points that are connected directly by a wire have…
the same voltage
What is electrical current is driven by?
A difference in voltage between different parts of the circuit.
Current can only flow through…
a looped path–a circuit must loop to form a continuous pathway back to where it started.
What type of voltage difference does a battery hold?
A constant voltage difference between its two contacts.
What does a light bulb produce?
Light, based on how much current passes through it.
A switch doesn’t connect the wires on either side until…
It is closed, or switched “on”. Once a switch is closed, it acts the same as a wire.
For components in series, the magnitude of the voltage drop across a component is proportional to…
that component’s resistance.
What happens to the resistance and total current when there are more paths for the current to flow?
The resistance goes down and the total current goes up.
