In a circuit diagram, the long line associated with an energy source indicates the _____________ terminal.
neutral
negative
positive
electrode
In a circuit diagram, electrons leave from which end of the source?
positive terminal
negative terminal
i don't know
they aren't moving!
At which terminal do the electrons return to the energy source in a circuit?
positive terminal
negative terminal
they get used at the load
still learning this.
SELECT ALL THAT APPLY: In current electricity, there exists a relationship between the following quantities:
Voltage and resistance (V : R)
resistance and current (R : I)
voltage and current (V : I)
resistance and circuit length (the further electrons travel, the more resistance they encounter)
In a series circuit, the flow of (a) follows only one path.
A toaster and a kettle are two loads on a series circuit. If the fuse for that outlet blows, which device will continue working?
both will continue working
neither will continue to work
only the kettle will continue working
only the toaster will continue working
