My brother [11 years old] has a homework question to do with electricity. I go blank when the subject of electricity is involved, so I found this forum.
His question is:
You have wires, 2 cells, 1 ammeter, 1 voltmeter, 4 lamps, a switch.
Create a circuit, using these rules:
o Of the 4 lamps, 2 must be bright, and 2 must be dull.
o Switch must control the 2 bright lamps only
o Voltmeter to read voltage across cells
o Ammeter reads the current to the dim cells only.
This was our attempt..
Bulbs 1 and 2 are meant to be bright, while 3 and 4 are the dim ones.
If you wouldn't mind, some feedback would be great. Would this circuit work? Would those bulbs be bright/dim in accordance with the rules?
Thank you in advance.
