A sheet of aluminum foil will provide shielding against a stream of electrons. Note that a stream of electrons will have trouble getting through air itself. That's because electrons have extremely small mass (compared to atoms), and because the electrons in a stream would have to "break through" all the electrons defining the volume of all the atoms in the air through which they are moving.
Note that a stream of electrons in this case is notelectric current flow as we normally know it. We're talking about as stream of electrons as might emerge from an "electron gun" of some kind. There are real electron guns in cathode ray tubes (CRTs), and this is the source of the beam. But that beam wouldn't fair well trying to move through air, so the tube is highly evacuated. Electrons can be stopped quite readily, though if they are highly accelerated and strike metal targets, X-rays could easily result.

Can electricity still pass through a bulb which has fused?
If the bulb lights up then electricity is passing through the bulb. If the bulb doesn't light up then electricity is not passing through.
What stops light from passing?
An opaque object
How do colored filters change the color of an object?
They prevent certain wavelengths (i.e. colours) from passing through. This means that you only see the colours that do pass through. If the object itself is coloured this may result in it becoming invisible if the filter is one that stops the object's colour from passing through it.
What word do you use for objects that do not let light pass through them?
Opaque is the term used to describe an object or substance that stops all light passing.
What is a insulator and conductor?
A insulator is a object a that stops the traveling of heat, electricity, and other stuff. A conductor is a thing that lets heat or electricity go through it.
How is water decomposed into its constituents?
By passing electricity through it.
What are materials called that stop electricity passing through them?
insulators
What separated water?
Passing electricity a through a molecule of water
Can electricity still pass through a bulb which has fused?
If the bulb lights up then electricity is passing through the bulb. If the bulb doesn't light up then electricity is not passing through.
What halogen is made by passing electricity through salt water?
Chlorine gas.
How well do people conduct electricity when you touched something electrical?
Human body is a good conductor of electricity when touched by electricity passing through something
Electricity stops when the circuit is?
Electricity stops as soon as the circuit opens.
Does salt water passing through a magnet create electricity?
no salt is non magnetic
What can separate water?
Passing electricity a through a molecule of water
Describe how fuse can be used as a protective system?
A fuse is a protective system in itself as it regulates the voltage passing through it and stops the flow of electricity if the current becomes too much. A fuse is designed to handle a certain amount of watts. If this limit is exceeded, then the fuse blows and whatever was being powered by that electricity is not damaged
How is the number of units of electricity consumed by motor in 2 hours calculated?
You can buy a volt meter, which can calculate how much electricity is passing through the wires.
The process of passing electricity through water to chemically separate it into hydrogen and oxygen is call?
It is called electrolysis.
