Question

Which components do all circuits have in common? Select three options.

energy source
voltmeter
wires
ammeter
device that needs electrical energy

Answer 1

as a hint, wires **are** a part of all circuits (otherwise the electricity won't flow), while ammeters are not (ammeters measure current but they're not necessary for the circuit to run)

do you have any ideas about the other choices?

Answer 2

um

Answer 3

Is energy source like from a pole to make electricity

Answer 4

well, a typical energy source in a circuit would be a battery, so you're on the right track

so yes, all circuits have "energy source in common". so far we have energy source in common + wires as 2 out of the 3 options.

any ideas what might be the third component common to all circuits?

Answer 5

Wires

Answer 6

and Voltmeter

Answer 7

mmm not quite. a voltmeter measures voltage but a circuit will run fine without it.

Answer 8

since we eliminated ammeter and voltmeter, that narrows us down to

energy source
wires
device that needs electrical energy

Answer 9

ok

Answer 10

Thank you
