No, not at all, current can flow between any two opposite poles. Usually a power source and wire are used, but current flows through lightning and such.

What energy transformation takes place in a flashlight?
Battery (chemical energy) goes to the wires (electrical energy) which goes to the light bulb (thermal and electromagnetic energy. In the bulb of a traditional flashlight, electric current energy is transformed to heat and then partially to light, when the temperature of the filament in the bulb is sufficient. In an LED type flashlight, little heat is produced and more of the electrical current energy is transformed into light.
What 2 things do you need for a current to flow?
Potential difference and the conductor. A cell and a bulb. Some connecting wires. The bulb can be made glow by connecting the wires with the cell.
What does the intensity of light bulb indicate?
It indicates that the light bulb must be high of voltage trough the current......
What three objects make a light bulb glow?
A power source (of electricity), a means to transport this power (conductors/wires), and the light bulb itself
What makes a light bulb light up?
When an incandescent light bulb (the normal round ones that Thomas Edison invented) is placed into a "hot" circuit, (meaning there is electricity flowing through it), the electricity passes through the filament (little metal wires) on the inside. As the electricity passes through it, the wires heat up and make a chemical reaction causing light to be emitted.
If there are more wires does the light get brighter?
No. Or at least not perceptually. The wires only supply electricity to the bulb - the bulb is what limits the current.
What makes the light bulb get brighter?
by shorter wires or thiker wires
How do you make a battery light a light bulb?
Make a circuit with 2 wires a batery and a light bulb and touch wire to medle on light bulb
What is bulb and its proccess?
A light bulb is an electric light that uses the process of a filament wire that is heated to produce an electrical current. When the electrical current passing throught the light bulb it produces light.
How does light turn on and off with no switch and light and no wires?
Perhaps by unscrewing the bulb light.
Does closed circuits work?
Closed circuits work, they have all the wires connecting from the battery, the switch and the lightbulb that is needed for the electrical current to flow through the battery through the closed switch into the light bulb and back into the battery. Therefore it works.
What is needed to light a light bulb?
Electricity has to pass through the filament which, when it gets hot enough from resistance to the current, begins to glow and give off light.
What do the support wires do on a light bulb?
As the name implies, support wires support the filament wire in the bulb, The filament, of course is the wire that glows white hot, giving out light

How to change a open circuit to a closed circuit?
u need a battery 2 wires and a light bulb. Step 1. Get the 2 wires and connect them to the battery step 2. connect the other side at the bottom of the light bulb the light bulb should light if it doesn't :(
How can you change a closed circuit to a open circuit?

If you have a thick wire attached to the positive terminal of a battery attached to a light bulb attached to a thin wire of the same length will the current be the same in both wires?
Yes; the current will be zero, because--as described--the wires are not connected in such a manner as to create a circuit.
