Anst 5. which circuit ould the light in bulb glow? mains ara. lal charge wood ect

Circuit #1).
The bulb wouldn't glow at the moment the photo was taken,
     because the switch is open, and there is no continuous path
     for electric current.
But as soon as the switch is closed, it will.

Circuit #2).
The bulb will not glow.  The switch is closed, but there is no
energy source in the circuit, like a battery.  It's nothing but a
piece of wire connected between the ends of the light bulb.

Circuit #3).
The bulb will not glow, because there is an insulator in the circuit (the wood), and electric current can't flow through it.

Circuit #4:
This is the circuit that works !
There is a battery, and the switch is closed.
So current flows from the battery, through the switch and the bulb,
    and back to the battery.
