Current Electricity SNC 1X

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 _____________ 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
