A cathode ray is a type of this technology.
What is a vacuum tube.
These are electronic signals that are a smoothly varying signals produced by a continuously changing the voltage in a circuit.
What are analog signals.
I neutral object held near a charged object can become charged by this means
What is induction.
When a pathway through which charges can move forms suddenly, this occurs
What is static discharge.
In pure form these two substance are poor conductors.
What are silicon and germanium.
These are made by adding trace amounts of boron to silicon or germanium.
What are p-type semiconductors.
These are used to change an alternating current into a direct current, turn a current on or off, or increase the strength of a signal..
What are vacuum tubes.
Walking across a carpet is an example of charging through this method.
What is friction
This is the SI unit for electric charge
What is the coulomb.
This is the transfer of excess electric charge through a conductor to Earth.
What is grounding
This is a solid state component that combines an n-type and a p-type semiconductor.

What is towards the charge.
This is the SI unit for current.
What is Ampere.
This is the difference on electrical potential energy between two places in an electrical field.
What is potential difference.
These make communication devices more portable reliable and affordable.
What are intergraded circuits known as microchips.
These are made from crystalline solids that conduct current only under certain conditions
What are semiconductors.
This is directly proportional to the amount of charge and inversely proportional to the square of the distance between the charges.
What is electric force.
Power is the product of these two sources.
What are voltage and current.
