Howstuffworks "How Batteries Work"
Illustrated explanation of battery function, types, and chemistry; related links.
Good basic introduction to how batteries work.
To do these experiments accurately, you will want to purchase an inexpensive ($10 to $20) volt-ohm meter at the local electronics or hardware store
Make sure that the meter can read low (in the 1-volt range) and low (in the 5- to 10-milliamp range)
Then measure the voltage and current by attaching your volt meter to the two pieces of metal

Jochen's High Voltage Page : Electronic high voltage meters
Be very careful with this. It does work and is accurate enough for hobbiest work.
Electronic high voltage meters Common voltmeters, digital or analog, usually range to some hundred volts maximum
However, the range of any voltmeter can easily be extended using extra series resistance, as shown in the figure
Calculating the necessary resistance implies knowledge of the input impedance of the voltmeter
For example, let's assume we want to extend the range of a standard digital voltmeter (input impedance 10MOhm) to 100kV
The maximum DC voltage the meter can take is 1000V
This means we need an external 1GOhm high voltage resistor in series with the meter
The total voltage ios given by the value indicatedby the meter, times 100
If we wanted to read the voltage in kV directly, we would need a resistor 1000 times as large as the input impedance of the voltmeter, i.e
If the resistor fails, the voltmeter will most probably see the total high voltage and will also fail (more or less spectacularly!)
For AC voltages, capacitive input impedance of the meter and capacity of the probe must be matched, which is difficult to achieve because of parasitic capacitance of the resistor chain
