9/3 = 3 volts per millimeter = 3,000 volts per meter.
The battery connected to the bulb has the potential chemical energy in it when it is connected by means of wire to the bulb the chemical energy in the battery is converted to the electrical energy which flows through the wire to the bulb glows the bulb which is a form of light energy after some time the bulb starts emitting heat which is heat energy.
The first piece that connects to the battery, which is on the far left side, the second piece up, needs to be placed so that it is connected to the battery on the right with a connection on the top and the bottom.
• In a parallel circuit, there are junctions in the circuit so the current can flow around the circuit in more than one way. • In a series circuit the current decreases as more bulbs are added. •In a parallel circuit, as more bulbs are added, the current increases. • This is because bulbs added in parallel offer less resistance
Look at where the battery is placed and you'll see one square with a piece that has three ends right to the left of the battery. This is the start of the circuit and this piece has to be placed so one end is connected to the battery and the other ends are point up and down. From there, the rest of the circuit should be pretty easy to figure out. Good luck! :)
To make a small electromagnet all you need is an iron nail and some fine isolated wire. Wind a couple of feet of the wire around the nail then connect one side of the wire to the positive side of the battery and the other to the negative. At the moment they are connected to the battery the nail is a magnet and as soon as the power comes of it will have lost most of its magnetism. Just an ordinary torch battery will do.

Sereies, with each cell about 2.2volts
parallel
Both resistors will have the voltage of the battery.
An ammeter must be connected in parallel to the circuit. If you do not understand the difference between parallel and series connection then you should leave it to a competent mechanic/electrician.
Voltage sources connected in parallel should have equal voltage. Otherwise the stronger battery would attempt to charge the weaker creating a lot of heat and depending on the type of battery there is the chance of explosion.
When you have a light bulb in front of each other (all connected to wires to a battery)
If each battery is identical, yes.
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
no..... The battery with lower voltage will consume power from the higher one...
A == B (- 12V +) (- 12V +) (- 12V +) A single 12V battery in series with 4x 12V batteries connected in parallel... Total voltage from A to B is 24 volts! Note that the single battery in series will limit the total current capacity to that of a single battery.
If each lamp is connected in parallel, then there are three 'paths' that draw current from the supply.
