(Not flowing) is due to an accumulation of electric charge on an object. Electric Charge is detected with an electroscope.
Law of conservation of charge
States that electric charge cannot be created or destroyed but can only be transferred from one object to another.
Conductors allow the passage of electrons easily. Ex. Metals such as copper or silver or gold Insulators are materials in which electrons are not able to move easily. Ex. Rubber or glass
Charge by conduction (contact) or charge by induction (coming near a charge)
Difference is the force that pushes electrons. Measured in Volts (the energy behind an electron,
Is the flow or net movement of electrons. Measured in Amperes (amps) (the number of electrons)
Opposes the flow of electrons. Measured in ohm's more resistance = less current
Conductors have a low resistance
Insulators have a high resistance
Relates voltage, current and resistance
Current x resistance
Is a path for electric current to flow
Is an incomplete path - does not allow current.
Has only one path for the current. If one light goes out they all go out.
Has more than one path for the current to flow. If one light goes out the rest stay lit. Current flows from high voltage to low voltage
